title: Persistence of the cardinal veins and thrombosis: CT demonstration.
abstract: A young man presented with extensive bilateral deep venous thrombosis of the lower extremities, recurrent over a 3 year period. Computed tomography revealed persistence of the abdominal cardinal venous system with azygous drainage of the abdominal veins into a normal right superior vena cava. The possible relation of the peripheral venous thrombosis to this venous anomaly is discussed.
