Abstract
We present an extremely rare vascular variation in which the accessory left renal vein (LRV) draining the lower pole of the left kidney drains into the left ovarian vein (LOV). A 35-year-old woman underwent a contrast-enhanced computed tomography (CT) of the abdomen with the clinical symptom of abdominal pain. Unexpectedly, an accessory LRV draining into the LOV was noted. Otherwise, the CT scan was unremarkable. Here we report a case of an accessory LRV draining into the LOV which has not been previously reported in the literature. Recognition and reporting of this anatomic variation is of paramount importance before the surgical or endovascular procedures involving the left kidney, left ovary, and retroperitoneum.
