Intralobar lung sequestration with systemic coronary arterial supply

Abstract.

Pulmonary sequestration is a rare anomaly. An accurate pre-operative evaluation of its vascular supply is essential for the surgeon's operative approach. We describe here an intrapulmonary sequestration with vascular arterial supply via the left circumflex and the right coronary artery. This case demonstrates that if aortography is unrevealing, then a coronary source should be considered in the preoperative search for the arterial supply to a pulmonary sequestration. Moreover, pulmonary sequestration should be listed in the differential diagnosis of aberrant coronary arteries.
