title: [A case of sarcoidosis with primary pulmonary cavitation].
abstract: A 30-year-old woman presented with multiple nodular shadows which enclosed a cavity on a chest radiograph. Chest computed tomographic (CT) images showed mediastinal lymphadenopathy, and multiple nodular opacities enclosing a cavity. Histopathological findings of biopsy specimens from the lung and mediastinal lymph nodes revealed noncaseating epithelioid cell granulomas without any evidence of Mycobacterium or fungal growth. The lesion in the lung included granulomatous vasculitis. Even without corticosteroid or any other therapy, the lung lesions resolved and the cavity disappeared. We report a case of sarcoidosis with primary acute cavitation.
