title: An Unusual Cause of a Solitary Lung Cavity.
abstract: Sarcoidosis is a systemic granulomatous disease of unknown etiology. Pulmonary involvement is common, but lung nodules in sarcoidosis are uncommon, and solitary nodules that cavitate are extremely rare. Nodular sarcoidosis is usually found in young, healthy, predominantly female individuals. These lesions need to be differentiated from multiple other conditions, including neoplasms and granulomatous infections. A thorough workup for other etiologies of cavitary lung lesions is required for diagnosis. Despite an ominous presentation, nodular cavitary sarcoidosis portends a favorable outcome. We report a patient who presented with a solitary cavitary nodular lung lesion that was diagnosed as sarcoidosis after extensive workup.
