Retroaortic left renal vein (RLRV) draining into the left common iliac vein: a rare variant and its clinical implication

摘要

A 55-year-old known hypertensive woman with a family history of breast cancer and pancreatic cancer in first-degree relatives was referred by her general practitioner for an intravenous contrast-enhanced multidetector CT (MDCT) scan of her abdomen and pelvis. There was no MDCT evidence of malignancy; however, there was an incidentally detected retroaortic left renal vein (RLRV), coursing obliquely and posterior to the abdominal aorta, draining into the left common iliac vein just prior to the origin of the inferior vena cava (IVC) (figures 1 and 2). The patient gave no history of prior urological symptoms that may be associated with this anomaly.
