The Rarest of the Rare: Crossed Fused Renal Ectopia of the Superior Ectopia Type

Crossed fused renal ectopiais a rare congenital anomaly of the urinary systemwhere one kidneycrosses over to opposite side and the parenchyma of the two kidneys fuse. Herein, we present an atypical CFRE case whose renal anatomy does not exactly match any of the already defined CFRE types. Both of the kidneysare ectopic with the crossed ectopic right kidneylying superiorly and fusedto the upper pole of the left kidney. Renal arterieswere originating from the common iliac arteries. A focal 90% stenosis was observed on the right main renal artery. The patient is borderline hypertensive.
