No radiopaque renal or ureteric calculi, suspicious renal mass or hydroureteronephrosis is seen.
Two equal size right renal arteries entering the renal hilum and a single left renal artery. No pre-aortic left renal vein is seen. Retro-aortic left renal vein coursing obliquely and inferiorly and draining via a small tributary in to the lower inferior vena cava (IVC) at L3 level and via a large tributary in to the left common iliac vein at L4 level.
CT scan findings are suggestive of type IV left renal vein and right accessory renal artery (anatomical variants).
