Incidentally detected right partially fused, malrotated, supernumerary kidney

Abstract

Supernumerary kidney (SK) is an uncommon anomaly of the urinary tract, usually occurring on the left side. A rare case of a partially-fused, SK on the right side is presented. The diagnosis is made through the identification of a distinct pelvicalyceal system along with its supplying renal artery and vein, utilising ultrasound, CT, or MRI. Contribution: Correct diagnosis of partially-fused, supernumerary kidneys based on imaging is crucial to avoid unnecessary procedures, so that asymptomatic cases are managed conservatively.
