Primary hepatic ectopic pregnancy in a patient with polycystic ovary syndrome: A case report

RATIONALE: Hepatic ectopic pregnancy is an extremely rare ectopic pregnancy. This study aimed to report a case of primary hepatic pregnancy in a patient with polycystic syndrome. PATIENT CONCERNS: A 30-year-old woman presented with vaginal bleeding after 63 days of amenorrhea. DIAGNOSIS: The patient was initially diagnosed with liver ectopic pregnancy using abdominal ultrasound and abdominal computed tomography (CT). INTERVENTIONS: The patient underwent laparoscopic exploration to reconfirm the gestational sac in the liver and abdominal surgery to remove liver gestation. The postoperative review of abdominal CT and the level of serum human chorionic gonadotropin (hCG) was performed. OUTCOMES: The postoperative pathological examination revealed a fluffy tissue in the liver tissue and a blood clot. The patient's vital signs were normal, and she was advised regular follow-up after discharge from the hospital. One month later, the serum hCG level reduced to 0.32 mIU/mL (reference range 0–5 mIU/mL). LESSONS: If the level of beta-human chorionic gonadotropin (β-HCG) is higher than normal in women of childbearing age and no gestational sac is found in the uterine cavity, the location of pregnancy and gestational sac should be positively confirmed. Also, the possibility of ectopic pregnancy in the abdominal cavity should be considered, and the relevant imaging and biochemical examinations should be improved to avoid delay in diagnosis and treatment.
