A rare congenital fusion anomaly of the urinary tract: Pancake kidney

Abstract

Pancake kidney is a rare subtype of cross fused renal ectopia. Fusion of both upper and lower poles of the kidney in pelvis results in a disc or cake shaped kidney appearence. In this report, we are presenting two cases (a 3-month-old male and a 3-year-old girl) with different presentations and their follow-up results. Usually, renal fusion anomalies do not pose a risk for deterioration of renal function. With this fact kept in mind, cases should be managed individually. Additionally, magnetic resonance imaging should be the preferred modality in which further evaluation is required since it can give both functional and anatomical detail with no radiation exposure.
