主动脉前方髂静脉汇合血管变异少见,认识其CT表现可避免误诊。作者报道2例。例1,女性44岁,因卵巢癌分期做CT检查。腹部平扫示肾血管平面以下,下腔与主动脉间角区有个1.6cm肿块,延伸超过4层(层厚8mm,间隔12mm),考虑似主动脉前髂静脉吻合。静注造影剂做动态扫描,见髂静脉均强化。 Aorta iliac vein convergence in front of vascular variability rare, understanding of its CT performance can avoid misdiagnosis. The authors report two cases. Example 1, female 44 years old, because of ovarian cancer staging do CT examination. Abdominal plain scan below the level of renal blood vessels, the lower chamber and the aorta with a 1.6cm mass in the corner, extending more than 4 layers (thickness 8mm, interval 12mm), consider the anastomosis of the anterior iliac vein. Intravenous contrast media do dynamic scanning, see the iliac vein are enhanced.
