A case of retrocaval ureter associated with double inferior vena cava, an exceedingly rare venous anomaly, is reported. This anomaly was correctly diagnosed by CT. CT after intravenous contrast injection showed the double inferior vena cavae on both sides of the abdominal aorta and the right ureter crossing the right inferior vena cava posteriorly. CT is a good diagnostic modality with which to demonstrate such a vascular anomaly, and the clinical usefulness of CT is stressed.
本文报道了一例下腔静脉后输尿管合并双下腔静脉（一种极其罕见的静脉异常）的病例。该异常通过CT得以正确诊断。静脉注射造影剂后的CT显示腹主动脉两侧有双下腔静脉，且右侧输尿管在右下方腔静脉后方交叉。CT是显示此类血管异常的良好诊断方法，强调了CT的临床实用性。
