Crossed Fused Renal Ectopia showing Pelviureteric Junction Obstruction with Single Ureter and Single Renal Artery

Abstract

Crossed fused renal ectopia is a rare anomaly remaining asymptomatic by far and detected invariably as either incidental finding or in view of pre-existing kidney disease. We report a case of crossed fused renal ectopia presenting as lumbar pain in a young female patient with no associated calculus or cystic kidney disease. It was an inferior type of renal ectopia on right side drained by a common artery and common ureter along with additional aberrant vascular supply. Multidetector computed tomography with multiplanar and three dimensional reconstruction helps in the proper delineation of renal fusion and ureteric anomaly if any, as well as mapping of aberrant vascular supply.
