A double left renal vein is a rare venous anomaly. During our routine gross anatomy course dissections, we found a double left renal vein encircling the aorta (renal collar) in a 72-year-old male cadaver. In our case, both these veins were draining into the inferior vena cava at different levels. The left suprarenal vein was draining into the anterior vein, and the left testicular vein was draining into the posterior vein. We searched the literature and discussed the clinical importance of this variation.
