Intralobar lung sequestration with systemic coronary arterial supply

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