Pulmonary sequestration infected with nontuberculous mycobacteria: a report of two cases and literature review

ABSTRACT

We report two cases of pulmonary sequestration infected with nontuberculous mycobacteria (NTM) Mycobacterium avium and Mycobacterium abscessus. Chest computed tomography showed pneumonic consolidation in the right lower lobe, which received a systemic blood supply from the descending aorta in both patients. Video-assisted thoracoscopic surgeries were successfully performed and pathological examinations revealed multiple caseating granulomas. A review of the literature revealed only seven previous case reports of pulmonary sequestration infected with NTM, and no case with Mycobacterium abscessus has been reported.
