Crossed Renal Ectopia without Fusion: An Uncommon Cause of Abdominal Mass

Abstract EN

Crossed renal ectopia is a rare congenital anomaly usually associated with fused kidneys (90%).

Most cases are asymptomatic and remain undiagnosed.

We report an unusual case of nonfused crossed renal ectopia.

The 11-year-old adolescent female patient was admitted with abdominal pain, anorexia, weight loss, and periumbilical mass.

Although the initial clinical suspicion was a tumoral lesion, abdominal ultrasound and magnetic resonance examination revealed crossed renal ectopia without fusion.

The renal ectopy was incidentally diagnosed, as described in 20 to 30% of cases.

In this case, the associated nonspecific symptoms were a coincidence.
