title: [Sarcoidosis presenting as a diffuse micronodular shadow on a chest radiograph].
abstract: A 36-year-old man was admitted to our hospital with chest-radiographic findings of diffuse ground-glass shadows in both lungs. A chest CT scan revealed disseminated micronodules with mediastinal lymphadenopathy. Histological examination of a transbronchial lung-biopsy specimen showed non-caseous epithelioid cell granulomata. Marked lymphocytosis and an abnormally high CD 4/CD 8 ratio was found in bronchoalveolar lavage fluid. These findings suggested a diagnosis of sarcoidosis despite the atypical radiographic findings.
