Crossed Fused Renal Ectopia With Acute Pyelonephritis: A Case Report.

Crossed Fused Renal Ectopia (CFRE) is a very rare anomaly of the kidneys with a prevalence of 1 in 1000 live births. In this condition, both kidneys are fused together on one side of the spine. Usually, CFRE is an asymptomatic condition and is mostly detected incidentally, but sometimes the patient may develop various renal signs and symptoms. We report a case of acute pyelonephritis in a crossed fused right renal ectopia which was diagnosed by renal ultrasound and confirmed by computed tomography in a 75-year-old female.
