Abstract

A 44-year-old man with an isolated anomaly of azygos continuation of the inferior vena cava (IVC) presented with dyspnea due to pulmonary thromboembolism and deep-vein thrombosis (DVT). Sonographic examination disclosed not only pulmonary hypertension and DVT, but also infrahepatic interruption of the IVC with azygos continuation. A rare anomaly of azygos continuation of IVC could cause DVT and pulmonary thromboembolism. Vascular echo could play an important role in the examination of DVT and/or venous anomalies.
