This article is about a case of hepatic ectopic pregnancy. A patient suffered from an acute abdomen with 14-day vaginal bleeding. A serum, human chorionic gonadotrophin (HCG) of 8,988 mIU/mL revealed a bit of pelvic effusion. A computed tomography (CT) plain scan displayed a polygonal, moderate density shadow of the left liver lobe. An enhanced CT had no sign of intensification. A magnetic resonance imaging (MRI) plain scan was undertaken. On a T1-weighted imaging (T1WI), the lesion appeared to be a low signal; on a T2-weighted imaging (T2WI), the lesion appeared to be a high signal. With enhanced MRI, the lesion showed an irregular mild plague-like intensification during the venous phase. It was excised by an operation and chorionic tissue was seen under a microscope. The result of pathological diagnosis was hepatic ectopic pregnancy.
本文报道了一例肝异位妊娠病例。一名患者出现急腹症并伴有14天的阴道出血。血清人绒毛膜促性腺激素（HCG）为8988 mIU/mL，显示有少量盆腔积液。计算机断层扫描（CT）平扫显示左肝叶有一个多边形、中等密度阴影。增强CT未见强化迹象。进行了磁共振成像（MRI）平扫。在T1加权成像（T1WI）上，病变表现为低信号；在T2加权成像（T2WI）上，病变表现为高信号。增强MRI检查显示，病变在静脉期呈不规则轻度斑片状强化。通过手术切除病变，显微镜下可见绒毛组织。病理诊断结果为肝异位妊娠。
