Bilateral hilar lymphadenopathy, with or without lung parenchymal infiltrates, is the most common radiographic finding in patients with sarcoidosis. Atypical pulmonary findings have been uncommonly reported and include multiple large lung nodules, cavitation, lobar collapse, pleural effusions or pneumothorax. ⋯ In patients exhibiting unusual pulmonary manifestations, diagnosis of sarcoidosis relies on compatible clinical signs, evidence of non-caseating granulomas, and exclusion of underlying conditions including infections, malignancy and other granulomatous diseases (Wegener disease, pneumoconiosis).
