Crossed fused ectopic kidneys are a rare renal anomaly. The autopsy prevalence of renal ectopia is more than clinical prevalence. Most presenting symptoms of crossed ectopic kidneys are nonspecific and most cases remain asymptomatic through their life and are diagnosed incidentally. The presented case was a 5 years old girl who suffered from episodic left flank pain that imaging findings on sonography and also technetium-99m dimercaptosuccinic acid (DMSA) scintigraphy indicated crossed fused ectopic kidneys.
