ABSTRACT
An 81-year-old woman was admitted to our hospital because of low-grade fever for 2 months. Chest computed tomography (CT) showed diffuse small nodular shadows in both lung fields. Bronchofiberscopy was performed, and Mycobacterium avium was cultured from a specimen. The patient underwent video-assisted thoracoscopic lung biopsy. Histological findings showed subpleural and perivascular granulomas, which indicated hematogenous dissemination of mycobacteria. M. avium was cultured from biopsy specimens, and the patient was diagnosed with disseminated nontuberculous mycobacteriosis. She was treated with clarithromycin, rifampicin, ethambutol, and amikacin, and the small nodular shadows on chest CT subsequently dissolved. The patient was human immunodeficiency virus (HIV)-antibody negative, and we could not identify any other immunodeficiency diseases.
