Crossed Fused Ectopic Kidney: A Case Report

Abstract

Crossed fused ectopic kidney is an unusual congenital malformation of the urinary tract. This condition is usually identified in the autopsy specimen rather than in general clinical scenario. In this condition, both kidneys are located on one side of the midline and are fused with each other. This condition is generally asymptomatic and usually diagnosed as incidental finding. We came across a case of crossed fused left to right ectopia with inferior infusion with nephroptosis. Generally, in cases of crossed fused renal ectopia, one kidney is lower than the other one but in our report, both kidneys were present at the same level. Initially it was thought as cake kidney, but on careful inspection diagnosis of crossed fused left to right ectopia with inferior infusion was made. During workup of abdominal pain, this finding was detected with no gross abnormality except for a tiny calculus. After detailed discussion with the patient, regular follow up was done without any active intervention and during that period he remained clinically and radiologically stable. So in these conditions active intervention is not always mandatory and patient may remain asymptomatic without any intervention.
