title: Imaging diagnosis of hepatic ectopic pregnancy: A report of one case.
abstract: 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.
