Figure 1.

A 66-year-old male with bronchiectasis and nontuberculous mycobacterial lung disease caused by Mycobacterium abscessus subsp. bolletii. (A) Chest radiography revealed bilateral multifocal tram-track signs (black arrows), suggesting bronchiectasis. (B) A transverse chest computed tomography scan (3.0-mm-section thickness) revealed bilateral bronchiectasis (white arrows) in the middle right lobe and the lingular segment of the upper left lobe as well as multiple tree-in-bud appearances (black arrows), suggesting bronchiolitis in both lungs.
