This was a case report from Vietnam of a hepatic ectopic pregnancy involving a 23 week old fetus. The patient was 27 years old with a history of fallopian tube surgery (which may explain the ectopic implantation). An ultrasound scan 2 months prior had not found the fetus. A repeat scan found a viable fetus in the liver with a beating heart. CT imaging found a placenta invading the right liver with blood supply from the right hepatic artery.
Unfortunately, surgery was complicated by massive haemorrhage and neither baby nor mother survived.
Hepatic ectopic pregnancies are extremely rare with <50 cases reported. This occurs when a fertilised egg escapes outside the reproductive system (eg by rupturing through the Fallopian tube into the abdominal cavity) and attaches onto the liver surface. Risk factors include ovarian or tubal pathology and pelvic inflammatory disease.
Although abdominal ectopic pregnancies have occasionally been viable, the condition carries a high mortality rate with no successful deliveries of hepatic ectopic pregnancies reported.
