Awareness of the variation and renal vascular abnormality at retroperitoneal space surgeries such as kidney surgery and transplantation is very important and necessary. Complexity in the veins development of the kidney area of fetus leads to a series of changes in the production of these veins, including the extra kidney vein, and the posterior aorta vein. In this case report, we present a case report of a 36-year-old male with a rare renal variation which has been identified with a simple abdominal Computed Tomography (CT) scan (16-slice). In this case report, there is a single renal vein which becomes two branches before drainage into Inferior Vena Cava (IVC) in which one of these branches passes anterior to aorta and the other posterior to aorta which suggests the type of circumaortic left renal vein.
