Crossed Fused Renal Ectopia

Abstract Crossed fused renal ectopia is a rare congenital anomaly. If at all detected, it is incidentally only. A 35-year-old female, during investigation for abdominal pain and lower urinary tract symptoms, was found to have an empty right renal fossa and left crossed renal ectopia with fusion on intravenous pyelography and ultrasonography. In our case, renal function was normal. This anomaly is frequently associated with other abnormal situations such as agenesis, vascular malformation, incontinence, a palpable abdominal mass, urinary tract infection, high incidence of stone formation, and genital anomalies. The importance of adequate imaging is being emphasized through this case report.
