title: A symptomatic atypical mycobacterial infection masquerading as a vascular ring on chest x-ray.
abstract: Atypical mycobacterium is rare in children. There are few case reports of childhood pulmonary diseases caused by atypical mycobacterium. The case of a 20-month-old boy who had stridor and respiratory distress is presented. Chest x-ray showed right-sided narrowing of the trachea and left-sided aortic knob. Ziehl-Neelsen stain showed acid-fast bacilli. The culture showed Mycobacterium malmoense.
