Abstract

A 2.5-year-old boy with a history of the previous incidental finding of an ectopic kidney in ultrasonography was referred to our nuclear medicine center for 99mTc-DMSA renal scintigraphy. The scan showed an unusual type of ectopic fused kidneys on the right side of the lower abdomen. In this anomaly, kidneys were fused completely across the medial portion of both upper and lower poles, as well as hilum with no septum. Each kidney, however, demonstrated separate consists of own collecting system. 99mTc-DMSA renal scintigraphy is a valuable imaging detection of different shape anomalies such as pancake kidney. We report this extremely rare case of ectopic fused types of renal anomaly including pancake kidney.
