title: Rare case of right accessory renal artery originating as a common trunk with the inferior mesenteric artery: a case report.
abstract: Dissection of a male cadaver revealed several vascular abnormalities in the abdominal cavity, notably of the renal circulation. In particular, three renal arteries were observed on the right side and two on the left. On the right side, one accessory renal artery originated as a common trunk with the inferior mesenteric artery. Additional variations included a left inferior phrenic artery originating from the celiac trunk, bilateral testicular veins emptying into renal veins, and the left testicular artery arising from the left renal artery. The possible embryonic development of these branching patterns and their clinical significance are discussed briefly.
