Intralobular pulmonary sequestration in the middle lobe supplied by a right internal mammary artery: a case report

Pulmonary sequestration (PS) is a rare congenital malformation that is more common in the left lower lobe, and the thoracic aorta is the most common arterial supply.

We describe a case of a 67-year-old man with a chief complaint of intermittent cough and hemoptysis who had been diagnosed by multidetector computed tomography angiography with right middle lobe intralobular pulmonary sequestration supplied by a right internal mammary artery. Finally, he underwent middle pulmonary lobectomy with normal postoperative recovery.

This is a rare intralobular pulmonary sequestration case for a feeding artery from the right internal mammary. Multidetector computed tomography angiography should be performed for diagnosis and preoperative evaluation once pulmonary sequestration is suspected.
