Portal vein aneurysms are rare. We describe a patient with an aneurysmal dilatation (3 x 4.5 cm) of the right portal vein. Real-time ultrasonography revealed an anechoic lesion communicating with the portal vein, suggesting a portal vein aneurysm. Colour Doppler, contrast-enhanced computed tomography, and portal venography confirmed the diagnosis. No evidence of portal hypertension was found. Follow-up examinations did not reveal a significant change in the size of the aneurysm after 18 months.
门静脉瘤较为罕见。我们描述了一名右门静脉出现动脉瘤样扩张（3×4.5厘米）的患者。实时超声检查发现一个与门静脉相通的无回声病变，提示为门静脉瘤。彩色多普勒、增强计算机断层扫描和门静脉造影证实了诊断。未发现门静脉高压的证据。随访检查显示18个月后动脉瘤大小无显著变化。
