Bilateral Crossed “Unfused” Renal Ectopia

Abstract

Ectopic kidney-uncrossed or crossed, or with and without fusion-is a common congenital developmental anomaly. Commonly employed imaging modalities used for evaluating such condition include ultrasonography, IV pyelography, and contrast-enhanced CT scan. Here in, we describe a rare case report of an incidentally detected bilateral crossed renal ectopia without fusion on Tc-DTPA scan in the setting of inconclusive ultrasonography and deranged renal function.

A Rare Case of Crossed Non-fused Ectopic Kidney

“…It can identify any hydronephrosis, hydroureter, renal calculi, or other urinary tract abnormalities [ 11 ]. A technetium-diethylenetriamine pentaacetate (99mTc-DTPA) scan can also be used to evaluate kidney function [ 15 ]. Laboratory investigations, especially renal function testing, can also be used to determine kidney function in the context of non-fused CRE.…”
