Sequestered hypoplastic pulmonary lobe supplied by the circumflex coronary artery in a patient with coronary artery disease: a case report.

Bronchopulmonary sequestrations are usually supplied by single or multiple branches from the descending aorta. We report on a rare form of sequestration of a hypoplastic mid-pulmonary lobe with arterial supply from the circumflex coronary artery coincidentally discovered during coronary angiography in a female patient with coronary artery disease and a history of recurrent hemoptysis. The patient underwent myocardial revascularization and resection of the sequestered lobe in a single-stage approach.
