Loading images...
Axial C+ portal venous phase
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.
Case Discussion
CT scan findings are suggestive of type IV left renal vein and right accessory renal artery (anatomical variants).
