An unusual case of persistent renal collar in a human adult male.
There are relatively few reports in the literature on accessory renal veins, and particularly that anomaly described as a persistent renal collar. The present paper describes a case in which a left renal vein is encountered in a human adult, both anterior and posterior to the abdominal aorta, though without a persistent left inferior vena cava.
