A sound knowledge of the normal and variations in blood supply of kidney is a prerequisite to having a favourable surgical outcome. Knowledge of the commonly occurring variations assumes even more significance in the era of diagnostic imaging and minimally invasive surgical approaches. We describe a case of variation of the renal blood vessel found during the routine dissection. A male cadaver, approximately of 60 years, presented an aberrant renal artery on the left side. Variation in the number, source, branching and course of the renal arteries occurs frequently. Any variation in arterial supply is important to clinicians undertaking surgery or other intervention renal procedures.
