1. To present a case of crossed fused renal ectopia that was incidentally discovered in a patient complaining of abdominal pain.
2. To be familiar with the complications and other possible pathologies associated with crossed fused renal ectopy.
Crossed renal ectopia is a rare congenital anomaly most often asymptomatic. We report a case of crossed fused renal ectopia where the fused kidneys were present on the left side forming an S -shaped configuration with two ureters arising from the fused kidneys. Our patient is a 63 year old male complaining of on and off epigastric pain with an elevated AFP levels. Triphasic liver scan was performed with I.V iodinated contrast revealed fused crossed renal ectopia.
