ABSTRACT
Circumaortic right renal vein is an extremely rare finding and to our knowledge only 1 case has been reported in the literature so far. Its rareness, in contrast to left renal vein anomalies, is thought to be due to a relatively simple embryologic development of right renal vein compared with left renal vein. On the other hand, association of Circumaortic right renal vein with inferior vena cava agenesis and aortic coarctation is an extremely rare occurrence. Our aim is to introduce a case of Circumaortic right renal vein in a 3-month-old child with inferior vena cava agenesis and aortic coarctation. Discussion on the underlying embryology of Circumaortic right renal vein, its clinical importance and the association with other vascular anomalies, will be on our focus as well. Precise understanding of renal vein anomalies is important when planning retroperitoneal surgery or interventional vascular procedures. Awareness of such anomaly implies crucial knowledge for radiologists who should include it in the medical reports to aid future patient's management.
