The potential ramifications of not being familiar with inflammatory pseudotumors and not knowing when to suggest it involve unnecessary and incorrect patient treatment including chemotherapy, and may have medicolegal implications for the radiologist. The differential diagnosis of pulmonary nodules (PNs) includes metastases, lung cancers, infectious diseases, and scar tissue, among others. Dall Bello AG, Severo CB, Oliveira Fde M, Hallal Junior RJ, Hochhergger B, Severo LC. To decide on the most likely or correct diagnosis may be challenging. They can signify disease processes affecting either the interstitium or the airspace. -, Narla LD, Newman B, Spottswood SS, Narla S, Kolli R. Inflammatory pseudotumor. Clinicopathologic correlation is always needed in such cases to establish a diagnosis, especially before initiating a new treatment. 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.When lung nodules occur in isolation (solitary pulmonary nodule (SPN), cancer is infrequently the case.But when there are several or many, the risk of cancer increases. Cavitation occurs most frequently in squamous cell tumors in comparison to adenocarcinomas and sarcomas which also cavitate occasionally. Approximately 50% of the nodules calcify or ossify (1,5). 2) lateral views revealed multiple rounded rather ill defined pulmonary nodules seen scattered throughout both lower lung zones being more numerous on the right side. There was no family history of cancer. 2002;17:252–8. We described a case of PHG, a rare clinico-radio-pathologic entity that should be in the differential diagnosis of multiple pulmonary nodules or masses. The differential diagnosis of multiple pulmonary nodules includes metastatic solid organ malignancy,…. Purpose . (PMID: 11112817), [6] BTS guideline. Sarcoidosis. Sarcoidosis is a rare differential diagnosis of pulmonary cavitary nodules. Both the CT and FDG PET characteristics, as well as the clinical scenarios, should be considered when characterizing multiple pulmonary nodules. Generally, the smaller the nodule, the more likely it is to be benign: 80% of benign nodules are less than 2 cm in diameter (, 6,, 9,, 12). 2b. The most common cause is histoplasmosis, in which the generally round or oval nodules are well circumscribed and often calcify. Differential diagnosis of multiple pulmonary nodules includes neoplastic, infective, immunological, and vascular causes (see box 1). Most nodules are noncancerous (benign). A month later, the nodule was slowly dissipating (arrow). The multiplicity of inflammatory nodules in this case, in the form of multiple pulmonary nodules and a spinal soft tissue mass, can be a considerable diagnostic challenge. Risk factors for malignant pulmonary nodules include a history of smoking and older age.
