Pancake Kidney Found Inside Abdominal Cavity: Rare Case with Literature Review

Abstract

The cake or lump kidney is a rare form of fusion. The pancake kidney is always found in the pelvic cavity, in the greater or lesser pelvis. However, we report a case of pancake kidney which was found inside abdominal cavity while investigating 32-year-old male for lower limb pain. CT scan with IV contrast reveals ‘fused mass situated in the right side of abdominal cavity with course uncrossed ureters opening separately into the urinary bladder found incidentally with patient work up’. Pancake kidney in this case was managed conservatively without any complication. This malformation is usually present in pelvic cavity, so blood supply is almost constant but in rare cases might be different and follows location of this anomaly.
