좌하엽으로의 비정상적인 체순환 동맥 공급 1예

A Case of Systemic Arterialization of the Lung without Sequestration

정상 폐로의 체순환 동맥 공급은 드문 것으로 알려져 있는데 저자들은 단순 흉부 X-선상 우연히 폐의 이상 음영을 발견하여 조영증강 전산화단층촬영상 좌하엽 저분절로 가는 체순환 동맥 분지를 진단한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

An anomalous systemic arterial supply to the normal basal segments of the left lower lobe without sequestration is a rare congenital anomaly. It differs from classical bronchopulmonary sequestration in that the involved lung retains a normal connection to the bronchial tree, although some place this entity exists within the broad framework of pulmonary sequestration. We experienced a case of a woman who presented with a nodular lesion on a chest X-ray. Contrast-enhanced CT diagnosed her as having an anomalous systemic arterial supply to the normal basal segments of the left lower lobe. This case is reported with a brief literature review.
