An incidentally diagnosed case: Persistent Left Superior Vena Cava

Abstract

Although persistent left superior vena cava (PLSVC) is the most common congenital anomaly of the thoracic venous system, it is a rare vascular anomaly. In this case report, we aimed to present the case of PLSVC which diagnosed incidentally in thoracic computed tomography (CT) performed for other reasons, draining to the coronary sinus and connecting with azygos-hemiazygos vein system, with imaging findings in the light of the literature. A 56-year-old patient who underwent thoracic CT examination with the complaint of chest pain, had a venous structure in the left half of the mediastinum that running lateral to the aorta and drained into the right atrium via the coronary sinus and a diagnosis of PLSVC was made. Even if it is asymptomatic, it is important to be recognized by radiologists as it may cause problems in cardiac surgery or catheterization procedures.
