ABSTRACT
One month before a 31-year-old man presented at our center, an abnormal shadow had been noted on his chest X-ray during a medical checkup. Computed tomography at a local clinic revealed a nodular shadow in his left lung, and he visited our center. Bronchial endoscopy was performed, and Mycobacterium simiae was detected in the cultured specimens. Transbronchial lung biopsy using endobronchial ultrasonography with a guide sheath revealed epithelioid cell granulomas, and he was diagnosed as having nontuberculous mycobacteriosis. Treatment with azithromycin, moxifloxacin, and sulfamethoxazole/trimethoprim resulted in a reduction in the abnormal shadows.
