Portal vein aneurysm, especially that of the extrahepatic portal vein, is a very rare entity. We recently observed a case of aneurysm at the junction of the superior mesenteric vein and the splenic vein which accompanied lupoid hepatitis. Abdominal ultrasonography, color Doppler ultrasonography, abdominal computed tomography (CT), magnetic resonance imaging (MRI), and angiography revealed a portal vein aneurysm that increased in size after a period of about 10 months.
门静脉瘤，尤其是肝外门静脉瘤，是一种非常罕见的病症。我们最近观察到一例在肠系膜上静脉与脾静脉交界处的动脉瘤，该动脉瘤伴有狼疮样肝炎。腹部超声、彩色多普勒超声、腹部计算机断层扫描（CT）、磁共振成像（MRI）及血管造影显示存在一个门静脉瘤，其大小在约10个月的时间里有所增大。
