Anomalies of major retroperitoneal vascular structures have been showed up in many reports so far. Here, a group of vascular anomalies of retroperitoneum were reported, all of which were encountered during the staging surgery of a 65-year-old woman with endometrium carcinoma. There was no vascular injury during the surgery associated with these vascular abnormalities. Since they are met quite frequently, it is important for surgeons dealing with retroperitoneum to be aware of the possible anomalies of vascular and renal structures in this region.
