Abstract

Hepatic ectopic pregnancy is an uncommon form of extrauterine pregnancy. A 31-year-old woman had acute abdominal pain and distention. Laboratory examination showed significantly increased serum β-human chorionic gonadotropin level. Both ultrasound and MRI identified a lesion located at the right lobe of the liver. FDG PET/CT was performed to determine whether the other causes of elevated β-human chorionic gonadotropin level, which showed an oval mass with mid peripherally increased FDG activity. After surgery, pathological results confirmed a diagnosis of hepatic ectopic pregnancy.

摘要

肝妊娠是一种罕见的异位妊娠形式。一位 31 岁的女性出现急性腹痛和腹胀。实验室检查显示血清β-人绒毛膜促性腺激素水平显著升高。超声和 MRI 均发现肝脏右叶有一处病灶。为确定血清β-人绒毛膜促性腺激素水平升高的其他原因，进行了 FDG PET/CT 检查，结果显示一个椭圆形肿块，周边中部 FDG 活性增高。手术后，病理结果证实为肝妊娠。
