A 54-year-old woman with bronchiectasis and nontuberculous mycobacterial lung disease caused by Mycobacterium lentiflavum. (A) A chest radiography reveals bilateral multifocal tram-track signs (white arrows). (B) A transverse chest computed tomography (CT) scan (2.5-mm-section thickness) on the level with the right inferior pulmonary vein reveals bilateral bronchiectasis (black arrowheads) in the right middle lobe and the lingular segment of the left upper lobe. (C) A chest CT scan obtained on the level with the superior segmental bronchus of the left lower lobe reveals bilateral bronchiolitis in both lungs (white arrowheads).
