Diagnosis of Rare Association of Orthotopic Multicystic Dysplasia with Crossed Fused Renal Ectopia

Abstract EN

Orthotopic multicystic dysplastic kidney with crossed fused ectopia is a rare congenital anomaly.

This congenital anomaly may give an appearance of a solitary kidney morphology during the initial imaging evaluation.

A solitary kidney should be carefully evaluated for the presence of duplication, horseshoe configuration, or crossed renal ectopy.

Vesicoureteral reflux is a common finding associated with a multicystic dysplastic kidney.

We present an infant with an orthotopic multicystic dysplastic kidney and an inferiorly placed crossed fused ectopic kidney.

The presence of a complex congenital anomaly may warrant further evaluation with cross-sectional imaging to depict the anatomy and structure.
