A case of right double inferior vena cava with circumcaval ureter.

ABSTRACT

Congenital inferior vena cava (IVC) anomalies are silent and detected incidentally on imaging. Double IVC is the most common IVC anomaly and is usually characterized by the presence of an IVC on each side of the abdominal aorta. In contrast, right double IVC, which is defined as two post-renal IVCs positioned to the right of the abdominal aorta, is seldom recognized. We report a rare case of a complete right double IVC with a circumcaval ureter that was incidentally detected by CT and describe the embryological and clinical implications.
