Interrupted Inferior Vena Cava with Hemiazygos Continuation in an Adult with a Persistent Left Superior Vena Cava and Left Single Coronary Artery: A Case Report

Congenital intrahepatic inferior vena cava (IVC) interruption with azygos/hemiazygos continuation is a rare congenital anomaly (1, 2) and hemiazygos vein continuation draining into the right atrium via a persistent left superior vena cava (SVC) is even rarer (3). Furthermore, a single coronary artery (SCA) ostium, in the absence of other cardiac disease, is an extremely rare coronary artery anomaly (4). We presented a very rare case of incidentally found interrupted IVC with hemiazygos vein continuation combined with a left SCA diagnosed by multi-detector computed tomography (MDCT). The dilated hemiazygos vein drained directly into the persistent left SVC.
