A lung nodule (or mass) is a small abnormal area that is sometimes found during a CT scan of the chest. Silicosis and coal worker’s pneumoconiosis both cause upper lobe nodules and masses that may have a characteristic appearance with an upper lobe distribution. We use cookies to help provide and enhance our service and tailor content and ads. Many of the radiographic features used in the analysis of the solitary pulmonary nodule can be used to advantage in the assessment of multiple lesions. Lung Cancer Screening: Benefits and Risks, How Cancer Spreads to the Lungs and What It Means for the Patient. Other less commonly encountered diseases that present as multiple pulmonary nodules include infections, arteriovenous malformations, Wegener's granulomatosis, and lymphoma. When a nodule is due to a metastasis from another cancer, there are often multiple lung nodules present. This can vary from one cancer type to the next. Diffuse pulmonary nodules are usually seen as multiple pulmonary nodular opacifications on a HRCT chest scan. If a calcium … The pleural spaces were clear. This will often be treated as a cancer. Miliary nodules are a particular form of nodular shadowing. There are many causes for lung nodules, but sometimes they can be the early stages of lung cancer, especially in older adults and smokers. Surgical techniques to take out pulmonary nodules include: Thoracotomy: This procedure is considered open lung surgery. Breast cancer as a systemic disease: a view of metastasis. Calcification of nodules is common and most often the result of a healed granuloma from tuberculosis or histoplasmosis. Mets, O., Chung, K., Scholten, E. et al. The presence of calcification may be virtually diagnostic of a benign granuloma, but this must be carefully considered. In cases in which angiosarcomas are formed by spindle cells, the tumor may resemble Kaposi sarcoma. The presence of other, more conventional areas of angiosarcoma and the use of immunohistochemical studies will lead to the correct interpretation, however. Multiple nodules do not mean that you are at more risk of lung cancer; what matters are the shape, size and location of these nodules. A retrospective study of a unique patient cohort. Reed JC, Multiple modules and masses. Does Stage 4 Cancer Mean That It Is Terminal? Tests for and symptoms of nodules. A single nodule could have multiple causes (infection, lymph node, cancer, others). A lung nodule or pulmonary nodule is a relatively small focal density in the lung. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. A larger lung nodule, such as one that's 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule. CONCLUSION: In patients with AIDS who have multiple pulmonary nodules at CT, nodule size and distribution are useful in the differentiation of potential causes. Tests for and symptoms of nodules. A chest radiograph (Figure 1) revealed two nodules projecting over the left upper lung field and one larger nodule projecting over the left middle lung field. Patients usually have to remain in the hospital for a … Thank you, {{form.email}}, for signing up. Multiple pulmonary nodules are most commonly encountered in patients with metastatic disease to the lungs. Nodules that are caused by metastatic cancers are usually numerous rather than a single isolated spot. Do not confuse the air crescent sign with the Monod sign (clinical history helps to differentiate). They can range from a few millimeters to up to 1 cm and when very small and numerous there can be some overlap with the term miliary nodules. Lung nodules can be found on up to half of all lung CT scans. Stereotactic body radiotherapy for oligometastatic disease in non-small cell lung cancer. Lung nodules will typically be seen as spots or lesions on an X-ray and measure 3 centimeters (roughly 1.2 inches) or less in diameter. They are a fairly common finding, occurring in between 3.9 and 6.6 of every 1,000 chest X-rays in the United States., When MPN are seen on a scan, the first assumption is cancer. They also can be a secondary cancer that metastasized in the lungs from a primary cancer elsewhere in the body. Could Solitary Pulmonary Nodules Be a Sign of Lung Cancer? 7.23 ) ( 2 ). Clinical Characteristics of Multiple Pulmonary Nodules with Ground Glass Opacity, The radiological spectrum of pulmonary lymphoproliferative disease, Differentiation of malignant and benign lung lesions with diffusion-weighted MR imaging, Pulmonary manifestations of the autoimmune lymphoproliferative syndrome. Doru Paul, MD, is triple board-certified in medical oncology, hematology, and internal medicine. Risk factors for malignant pulmonary nodules include a history of smoking and older age. 1 Among patients already diagnosed with cancer, data regarding optimal investigation of PNs are scarce. If the cause of your nodules is still unclear after imaging, a lung biopsy may be performed to obtain a tissue sample. If it’s larger, it’s called a mass. Ann Thorac Med. The lungs were otherwise clear. It shows up as a white spot on a LDCT scan. Let's look at the definition of a lung nodule, how it differs from a mass, and some of the characteristics of a nodule that may suggest it is either cancerous or non-cancerous. Nodules related to an infection can be treated with the appropriate antibiotic, antifungal, or antiparasitic drug. Hydatid disease is one of the most important helminthic diseases. Unlike early-stage pulmonary nodules, nodules caused by metastases are the result of a more serious, later-stage cancer. Thus, a range of times rather than a specific interval for follow-up computed tomography (CT… in 2013 that can be employed in the prediction of malignancy risk of lung nodules based on nodule size, count, consistency and location, as well as patient gender, family history and presence of emphysema. There are two main types of pulmonary nodules: malignant (cancerous) and benign (noncancerous). Nodules larger than 1 cm are often neoplastic. 2017;6(1):62-7. doi:10.21037/tlcr.2017.02.02. The imaging of small pulmonary nodules. Evaluation of old films is imperative. 1 Among patients already diagnosed with cancer, data regarding optimal investigation of PNs are scarce. ICD-10-CM Diagnosis Code R91.1. ... if known, such as:; multiple valve disease (I08.-); rheumatic mitral valve diseases (I05.-); rheumatic aortic valve diseases (I06.-); Group 2 pulmonary hypertension. Pulmonary manifestations of the autoimmune lymphoproliferative syndrome. ... if known, such as:; multiple valve disease (I08.-); rheumatic mitral valve diseases (I05.-); rheumatic aortic valve diseases (I06.-); Group 2 pulmonary hypertension. Diffuse pulmonary nodules are usually seen as multiple pulmonary nodular opacifications on a HRCT chest scan. Immunohistochemical studies using different types of keratins, CEA, and other carcinomatous epitopes may be useful in this aspect of the diagnostic investigation. A related issue, called multiple bilateral pulmonary nodules, are growths that have developed on both lungs. 2018;28(3):1095-101. doi:10.1007/s00330-017-5055-x, Sato, Y.; Fujimoto, D.; Morimoto, T.; et al. Blackley DJ, Halldin CN, Laney AS, et al. Differentiating the minority of malignant from benign IPNs represents one of the most urgent clinical problems in early detection of lung cancer, particularly on the eve of possible widespread adoption of lung cancer screening in the United States ().When managing IPNs, the majority of diagnostic errors occur in the intermediate probability group (Fig. The way that the nodules look on a scan can suggest which type they are. Cancerous nodules can be the first stage of a primary lung cancer, brought on by smoking or any other common cause of lung cancer. The second one also caused lung collapse. This is a simple model developed by McWilliams et al. 2-4 Usually, the emergence of PNs during treatment or follow-up leads clinicians to favor the hypothesis that disease has metastasized to the lungs. In general, malignant nodules double in size every one to six months. In more than 95% of immunocompetent patients with multiple pulmonary nodules, the etiology of the nodules is (a) metastases or (b) infection (typically tuberculous or fungal granulomas) ( Fig. Even if your nodules are cancerous, there are almost always treatment options available. The lung nodules may be caused by various conditions, such as lung lesions, infections, and certain lung diseases. Benign nodules can often be left alone. But "most common" doesn't mean "only." 7.22 ). Radiol Oncol. Jamil A, Kasi A. 15 Assessment of SPNs, both solid and subsolid, is clinically significant as it may be an early sign of lung cancer. Interpretation … “Multiple” pulmonary nodules is when 2 or more nodules are identified. No matter your medical history, being told that you have multiple lung nodules can be frightening. 2-4 Usually, the emergence of PNs during treatment or follow-up leads clinicians to favor the hypothesis that disease has metastasized to the lungs. The growth usually has to be smaller than 3 centimeters to qualify as a nodule. Lung A pulmonary nodule is usually 3 centimeters or smaller in diameter. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. The differential diagnosis for multiple pulmonary nodules is different from that for SPNs , although there is some overlap. in 2013 that can be employed in the prediction of malignancy risk of lung nodules based on nodule size, count, consistency and location, as well as patient gender, family history and presence of emphysema. ICD-10-CM Diagnosis Code R91.1. The more common ones can be broken up as follows. The list of primary tumors that metastasize to the lung is long. Multiple pulmonary nodules also have a wide differential diagnosis, including malignant (metastases, primary lung cancers, lymphoma) and benign (embolic, autoimmune, infectious) etiologies. Silicosis and coal worker’s pneumoconiosis both cause upper lobe nodules and masses that may have a characteristic appearance with an … Differentiation of malignant and benign lung lesions with diffusion-weighted MR imaging. Echinococcosis is worldwide in distribution; it occurs most commonly in sheep and cattle-raising areas [].Lung is the second most common involved organ but it is hard to distinguish pulmonary echinococcosis from a variety of other pulmonary lesions especially metastatic lesions to the lung. doi:10.1378/chest.12-2351, Redig AJ, Mcallister SS. One manifestation of SAD is multiple small nodules, which are often found abundantly along the bronchovascular bundles and histologically prove to be centered about abnormal bronchioles (Figs. Nodules with a slower or faster growth rate are less likely to be cancerous. In this setting, epithelial tumors such as carcinoma or melanoma enter into the differential diagnosis. There may also be multiple nodules. Diagnosis and management of lung cancer, 3rd ed: American College of Chest Physicians evidence-based clinical practice guidelines, Breast cancer as a systemic disease: a view of metastasis, Treatment of metastatic colorectal cancer: Standard of care and future perspectives, Frontline therapy for classical Hodgkin lymphoma by stage and prognostic factors, Stereotactic body radiotherapy for oligometastatic disease in non-small cell lung cancer. She’s still on Tarceva. What causes pulmonary nodules? Nodules larger than 1 cm are often neoplastic. Multiple pulmonary nodules are most often metastases from a distant primary tumor, but they must be distinguished from a number of inflammatory and infectious diseases that may cause multiple pulmonary nodules or masses.

From: Chest Radiology (Sixth Edition), 2011, James C. Reed MD, in Chest Radiology (Seventh Edition), 2019. The radiological spectrum of pulmonary lymphoproliferative disease. Eur Radiol. Am J Public Health. 17A and 17B). The prevalence of noncalcified lung nodules has been reported as 33% (range 17–53%) and 13% (range 2–24%), in a screening and nonscreening study population, respectively . Lung nodules are described as "spots" that are 3 centimeters (1.5 inches) in diameter or less (lesions larger than 3 cm are referred to a lung masses. Nodules smaller than 1 cm, especially those with a centrilobular distribution, are typically infectious. The purpose of these recommendations is to reduce the number of unnecessary follow-up examinations while providing greater discretion to the radiologist, clinician, and patient to make management decisions. 2017. doi:10.1177/1179554917731072, Wujanto C, Vellayappan B, Siva S, et al. Growths on the lung are referred to as multiple pulmonary nodules. Multiple nodules: Solitary nodules appear only in 1 lung. This is why it is important that you receive a full evaluation. One or more small lung nodules were seen on your low-dose chest Computed Tomography scan (LDCT) that was done as a screening test for lung cancer. Confirmation of consolidations rather than solid masses makes metastases unlikely. 2019;9:1219. doi:10.3389/fonc.2019.01219, Ⓒ 2021 About, Inc. (Dotdash) — All rights reserved, Lynne Eldrige, MD, is a lung cancer physician, patient advocate, and award-winning author of "Avoiding Cancer One Day at a Time. How Chest X-Rays Can Sometimes Misdiagnose Lung Cancer, Lung Cancer and FNA (Fine Needle Aspiration), Lung nodules: A comprehensive review on current approach and management. 2016;13(8):1279-88. doi:10.1513/AnnalsATS.201601-079OC, Khan AN, Al-Jahdali HH, Irion KL, Arabi M, Koteyar SS. They also can be a secondary cancer that metastasized in the lungs from a primary cancer elsewhere in the body. A nodule is a small round growth on the lung. Cancer, metastasis to the lung. Individual abnormal regions generally can be separated from other involved areas by normal or near-normal lung parenchyma. CONCLUSION: In patients with AIDS who have multiple pulmonary nodules at CT, nodule size and distribution are useful in the differentiation of potential causes. Benign tumors usually show little change or growth. With the introduction of multidetector computed tomography (MDCT), the number of detected lung nodules, particularly those small in size, has dramatically increased. Incidental perifissural nodules on routine chest computed tomography: Lung cancer or not? Multiple pulmonary nodules are most commonly encountered in patients with metastatic disease to the lungs. Of the other primary pulmonary neoplasms that may manifest in similar fashion, the most important is epithelioid hemangioendothelioma. Nodules smaller than 1 cm, especially those with a centrilobular distribution, are typically infectious. Echinococcosis is worldwide in distribution; it occurs most commonly in sheep and cattle-raising areas [].Lung is the second most common involved organ but it is hard to distinguish pulmonary echinococcosis from a variety of other pulmonary lesions especially metastatic lesions to the lung. Calcification of nodules is common and most often the result of a healed granuloma from tuberculosis or histoplasmosis. Because angiosarcomas may manifest as multiple pulmonary nodules, the possibility of metastatic disease from tumors outside of the thoracic cavity needs to be considered. They can signify disease processes affecting either the interstitium or the airspace. A larger lung nodule, such as one that's 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule. Pulmonary Nodule Cancer Probability. Cancerous nodules can be the first stage of a primary lung cancer, brought on by smoking or any other common cause of lung cancer. Cancerous pulmonary nodules … If you've had a chest X-ray and have been advised that the radiologist spotted \"multiple lung nodules\" or \"multiple pulmonary nodules,\" the first thing that may come to mind is cancer. They can signify disease processes affecting either the interstitium or the airspace. 1  Lung nodules are very common, especially in people who have smoked, but not all lung nodules mean lung cancer; there are many possible causes. 2017; DOI: 10.1111/resp.13089. On immunohistochemical studies, both tumors share the same immunophenotype of vascular differentiation. ", Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. Incidental perifissural nodules on routine chest computed tomography: Lung cancer or not?. Discussion. Central nervous system tumors least commonly lead to pulmonary metastases. Br J Radiol. Multiple pulmonary nodules are most frequently the result of metastatic disease. Those located in the upper portions of the lung are also more likely to be cancerous. We determined nodule count per participant. If you have any older chest X-rays, you should let your doctor look at them to determine the growth rate of the nodule. You might also hear it called a “spot on the lung”, “coin spot” or “coin lesion”. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans.. Note that the air crescent sign may also be seen in TB, actinomycosis, mucormycosis, septic emboli, and tumors. Additional imaging tests can be used, including: The current thinking among radiologists is that the combination of CT and PET scans is more useful in determining the cause of MPNs than the individual tests on their own.. Individual abnormal regions generally can be separated from other involved areas by normal or near-normal lung parenchyma. Loverdos K, Fotiadis A, Kontogianni C, Iliopoulou M, Gaga M. Lung nodules: A comprehensive review on current approach and management. The term miliary derives from the resemblance in size and shape of the nodules to millet seeds, being round, well defined, and 2 to 3 mm in diameter. Natural History and Clinical Characteristics of Multiple Pulmonary Nodules with Ground Glass Opacity. They can range from a few millimeters to up to 1 cm and when very small and numerous there can be some overlap with the term miliary nodules. Clin Med Insights Oncol. If metastatic cancer is diagnosed, treatment would be prescribed based mainly on the location of the primary tumor and the extent of the metastases. 8.8). Bu… In: Chest Radiology (Seventh Edition). A solitary pulmonary nodule or “spot on the lung” is defined as a discrete, well-defined, rounded opacity less than or equal to 3 cm (1.5 inches) in diameter that is completely surrounded by lung tissue, does not touch the root of the lung or mediastinum, and is not associated with enlarged lymph nodes, collapsed lung, or pleural effusion. Both the CT and FDG PET characteristics, as well as the clinical scenarios, should be considered when characterizing multiple pulmonary nodules. Diffuse pulmonary nodules (differential diagnosis) A number of differentials must be kept in mind while approaching diffuse or multiple pulmonary nodules. Multiple pulmonary nodules are most often metastases from a distant primary tumor, but they must be distinguished from a number of inflammatory and infectious diseases that may cause multiple pulmonary nodules or masses. A thin linear density could be appreciated, extending laterally from the larger nodule. More than 20% of participants in low-dose CT screening programs were found on their first scan to have one or more lung nodules that required further investigation. The presence of one calcified granuloma does not prove that other noncalcified nodules are benign granulomas. 2018;108(9):1220-22. doi:10.2105/AJPH.2018.304517, Gould MK, Donington J, Lynch WR, et al. 2013;274(2):113-26. doi:10.1111/joim.12084, Holch J, Stintzing S, Heinemann V. Treatment of metastatic colorectal cancer: Standard of care and future perspectives. Gary A. Ulaner MD, PhD, FACNM, in Fundamentals of Oncologic PET/CT, 2019. The differential diagnosis for subsolid solitary pulmonary nodules (SPNs) includes infection, inflammation, hemorrhage, and malignancy (commonly lung adenocarcinoma). These well-defined nodules vary from solitary subcentimeter lesions to multiple lesions mimicking pulmonary metastases from malignant tumors. Further important clinical clues may come from the clinical status of the patient. Murphy A, Gaillar F. Coal workers' pneumoconiosis. The evolution excludes the diagnosis of metastases. A pulmonary nodule is considered small if its largest diameter is 10 mm or less. In Tumors and Tumor-Like Conditions of the Lung and Pleura, 2010. Metastases are most commonly round nodules; thus the presence of multiple FDG-avid patchy nodules may suggest a different diagnosis (Fig. MPN may be caused by malignant or benign diseases. These scans are done for many reasons, such as part of lung cancer screening, or to check the lungs if you have symptoms. The lungs were otherwise clear. What Are Benign Lung Nodules and Benign Lung Tumors? 2011;1(2):39-51.. doi:10.4103/2231-0770.90915. “Multiple” pulmonary nodules is when 2 or more nodules are identified. Likewise, in a patient with lymphoma, multiple round nodules in the lungs should be considered lung lymphoma until proven otherwise (Fig. And while cancer may be the cause, there are other possible explanations. Pulmonary nodules (PNs) are frequently encountered on imaging studies and represent a diagnostic challenge. Transl Lung Cancer Res. In a patient with a malignancy with propensity to metastasize to the lung, multiple round pulmonary nodules should be considered suspicious for lung metastases, whether FDG avid (Fig. A pulmonary nodule is a round or oval-shaped growth in the lung. The pattern of large, multifocal ill-defined opacities that evolve to smaller, sharply defined nodules over a period of weeks to months indicates either healing granulomas or organizing infarcts to be the cause of the nodules. A chest radiograph (Figure 1) revealed two nodules projecting over the left upper lung field and one larger nodule projecting over the left middle lung field. 2016;32(3):178-83. doi:10.1159/000446052, Allen PB, Gordon LI. Immunostaining for S-100 protein, HMB-45, and Melan A should help in distinguishing melanoma from angiosarcoma. If you've had a chest X-ray or other imaging and have been advised that the radiologist spotted multiple lung nodules, the first thing that may come to mind is cancer. A common clinical presentation for this tumor is one of multiple pulmonary nodules; however, the histologic features of epithelioid hemangioendothelioma—namely, the presence of a myxoid or “chondroid-like” stroma and the lack of pleomorphism—will distinguish it from angiosarcoma. The treatment of MPN will depend on the cause. Sign up and get your guide! J Intern Med. These recipes focus on antioxidant-rich foods to better protect you and your loved ones. Cancerous pulmonary tumors grow rather quick and can double in size every four months. Diffuse multiple pulmonary nodules are the most characteristic radiologic findings in benign metastasizing leiomyoma. A pulmonary nodule is … Most small solid pulmonary nodules are benign, 80% granulomas and intrapulmonary lymph nodes, 10% hamartomas and 10% other benign lesions. A cut is made in the wall of the chest in order to remove pieces of diseased lung tissue. Pulmonary nodules (PNs) are frequently encountered on imaging studies and represent a diagnostic challenge. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans. If it’s larger, it’s called a mass. Limiting processed foods and red meats can help ward off cancer risk. Diagnosis and management of lung cancer, 3rd ed: American College of Chest Physicians evidence-based clinical practice guidelines. Both the CT and FDG PET characteristics, as well as the clinical scenarios, should be considered when characterizing multiple pulmonary nodules. Clinical correlation is essential in suggesting parasitic diseases as a cause of pulmonary nodules. What are multiple pulmonary nodules? The patient is given CT scan and then rescanned on a pre-determined schedule (every six or 12 months). Since the most common cause of MPN is metastatic cancer, doctors will often begin their investigation by looking for a primary (original) tumor. Depending on what the early diagnostics say, the doctor may order a mammogram or breast magnetic resonance imaging (MRI) to look for a breast tumor, or a colonoscopy to look for a colon tumor. You might also hear it called a “spot on the lung”, “coin spot” or “coin lesion”. The appearance of the air crescent sign indicates the recovery phase (increased granulocytic response). There may also be multiple nodules. James C. Reed M.D., in Chest Radiology (Sixth Edition), 2011. As can be seen, both the CT and FDG PET characteristics of multiple pulmonary nodules are important for optimal diagnosis. If you have any older chest X-rays, you should let your doctor look at them to determine the growth rate of the nodule. 2012;85(1015):848-64. doi:10.1259/bjr/16420165, Gümüştaş S, Inan N, Akansel G, Ciftçi E, Demirci A, Ozkara SK. PSN or mixed nodules are a combination of both ground-glass and solid components, the latter obscuring underlying lung architecture (6). Solitary pulmonary nodule: A diagnostic algorithm in the light of current imaging technique. Discussion. Multiple nodules that are 8 millimeters (mm), roughly 1/4 inch, or more in diameter, Nodules described as "non-calcified" (with evenly distributed "ground-glass" appearance), Nodules that are less than 5 mm (1/5 inch) are more likely to be benign, especially when distributed in the fissures between the lobes of the lung or along the tissue that lines the lung, Nodules described as "calcified" (seen on X-ray with random spots and flecks). A micronodule is considered a pulmonary nodule <3 mm (6,7). She has been in hospital for 1 week on oxygen as she’s short of breath and weak. More than 20% of participants in low-dose CT screening programs were found on their first scan to have one or more lung nodules that required further investigation. A lung nodule or pulmonary nodule is a relatively small focal density in the lung.A solitary pulmonary nodule (SPN) or coin lesion, is a mass in the lung smaller than 3 centimeters in diameter. A pulmonary nodule is a rounded or irregular opacity, which may be well or poorly defined, measuring ≤3 cm in diameter . A nodule is a "spot on the lung," seen on an X-ray or computed tomography (CT) scan. Radiographically, multiple nodules are described in terms of size, number, distribution, density, definition, cavitation, speed of growth (if serial films are available), and accompanying pleural, mediastinal, or skeletal abnormalities. Multiple pulmonary nodules are distinguished from multifocal infiltrative diseases by their homogeneous appearance and sharply defined borders. It is usually 3 centimeters or less. The growth usually has to be smaller than 3 centimeters to qualify as a nodule. Benign tumors usually show little change or growth. Rheumatoid nodules can be solitary or multiple ( Fig. This will often be treated as a cancer. One or more small lung nodules were seen on your low-dose chest Computed Tomography scan (LDCT) that was done as a screening test for lung cancer. This is a simple model developed by McWilliams et al. If there are few, treating the malignant nodules may improve survival.. A single nodule could have multiple causes (infection, lymph node, cancer, others). Ann Am Thorac Soc. 8.7). A solitary pulmonary nodule or “spot on the lung” is defined as a discrete, well-defined, rounded opacity less than or equal to 3 cm (1.5 inches) in diameter that is completely surrounded by lung tissue, does not touch the root of the lung or mediastinum, and is not associated with enlarged lymph nodes, collapsed lung, or pleural effusion. In fact, cancer is the most common cause of MPN and is usually the result of metastasis (when cancer spreads from a primary tumor to the other parts of the body).. When lung nodules occur in isolation (solitary pulmonary nodule (SPN), cancer is infrequently the case. A thin linear density could be appreciated, extending laterally from the larger nodule. But keep in mind that many MPNs are benign, and some may not even require treatment of any sort. There are nearly as many benign (non-cancerous) causes of MPN as there are malignant (cancerous) ones. Other less commonly encountered diseases that present as multiple pulmonary nodules include infections, arteriovenous malformations, Wegener's granulomatosis, and lymphoma. The … Multiple pulmonary nodules also have a wide differential diagnosis, including malignant (metastases, primary lung cancers, lymphoma) and benign (embolic, autoimmune, infectious) etiologies. Commonly called a “spot on the lung,” a nodule is a round area that is more solid than normal lung tissue. Multiple pulmonary nodules are small round growths on the lung. For example, coal workers' pneumoconiosis most often causes nodules that are predominant in the upper lobes, while lymphoma typically manifests with nodules around the airways..
