CT diagnosis of retrocaval ureter associated with double inferior vena cava: report of a case.

Abstract

A case of retrocaval ureter associated with double inferior vena cava, an exceedingly rare venous anomaly, is reported. This anomaly was correctly diagnosed by CT. CT after intravenous contrast injection showed the double inferior vena cavae on both sides of the abdominal aorta and the right ureter crossing the right inferior vena cava posteriorly. CT is a good diagnostic modality with which to demonstrate such a vascular anomaly, and the clinical usefulness of CT is stressed.
