A 46-year-old man was found to have an asymptomatic superior vena cava duplication with a large dominant left superior vena cava, a hypoplastic right superior vena cava, and a left-sided azygos arch ...during a thoracic CT Scan. Persistent left superior vena cava is mostly found in the context of a superior vena cava duplication, but this is the first case to date of such an asymmetrical diameter between the left and right superior vena cava, associated with a left-sided azygos vein. Furthermore, the patient had always been asymptomatic and had no other cardiac anomaly or anatomic vascular variation.
