Abstract

Bronchopulmonary sequestration (BPS) is a rare congenital abnormality of the lower airway, generally characterized by blood supply received from the systemic circulation. We present a rare case of a 19-year-old man with incidentally detected BPS supplied by a branch of a pulmonary artery, rather than a systemic artery. Computed tomography showed a sequestered segment supplied by a branch of the left pulmonary artery and containing an ectopic bronchus. As chest computed tomography revealed necrosis in the sequestered tissue, infection was presumed, and the tissue was surgically removed. This may represent a very unusual occurrence, as such cases have yet to be reported in the literature.
