A 60-year-old woman was admitted to our hospital because of progressive cough and chest pain for 2 months. She also complained of exertional dyspnea. Bilateral diffuse infiltlative shadows were found on the chest roentogenogram. Ground-glass opacity in the middle lobe and lingula, and subpleural patchy consolidation were seen on the computed tomogram of the chest. Arterial oxygenation and diffusing capacity were low. The level of angiotensin-converting enzyme in serum was normal, but that of lysozyme was high. In the BAL (broncho-alveolar lavage) fluid, total cell count and the number of lymphocytes were high, and the CD 4/8 ratio of the lymphocytes was high. Open lung biopsy revealed numerous confluent sarcoid granulomas with necrosis, which strongly correlated with severe vasculitis. After necrotizing sarcoid granulomatosis was diagnosed, prednisolone was administered, which resulted in improvement of symptoms and disappearance of chest-radiograph shadows. Necrotizing sarcoid granulomatosis may be seen as a variant type of sarcoidosis. However, clinical findings including the chest-radiograph shadows and clinical course of this case differ from those of ordinary sarcoidosis. These clinical findings can be attributed to severe vasculitis, as revealed by histological examination.
