Primary hepatic pregnancy

Successful Management of Abdominal Pregnancy: Two Case Reports

Abdominal pregnancy is a rare, life-threatening condition defined as pregnancy in the peritoneal cavity exclusive of tubal, ovarian, or intraligamentary locations. It can be primarily located in the peritoneal cavity or secondary to a ruptured ectopic pregnancy or tubal abortion. We present two cases of abdominal pregnancy, one primary and another secondary, both diagnosed and successfully managed in our institution. The first patient, a para 2 at 14 weeks gestation, presented with abdominal pain, distension, and dizziness, which had started four days prior. The initial radiological scan reported an intrauterine pregnancy with ascites, but a bedside ultrasound revealed an empty uterus and a viable pregnancy located in the Pouch of Douglas (POD). This was a secondary abdominal pregnancy managed successfully by laparotomy. The second patient, a para 3 + 4 miscarriages with seven weeks amenorrhea was admitted with an initial diagnosis of pregnancy of unknown location. She had a beta human chorionic gonadotropin level of 14 444 mIU/mL. Diagnostic laparoscopy revealed a hemoperitoneum, bulky uterus, normal looking right and left adnexa, and a dense irregular bleeding tissue of around 3 × 4 cm firmly attached to the POD. The histopathology report of the tissue retrieved from the POD confirmed products of conception. This case report supports the importance of awareness and high clinical suspicion for such a life-threatening condition to avoid maternal morbidity and mortality. To the best of our knowledge, no previous cases of abdominal pregnancy have been reported in the UAE to date.

Ectopic pregnancy in the liver incidentally diagnosed by imaging: A case report

The present report describes the case of a 31-year-old woman diagnosed with an ectopic pregnancy in the liver. The patient presented with amenorrhea for 40 days and abdominal distention for 27 days. A liver mass had been detected 6 days prior to presentation. Using ultrasound (US), a hyperechoic mass with a fluid sonolucent area was detected in the right hepatic lobe. Examination by computed tomography (CT) revealed the presence of a mass in the right hepatic lobe with a slightly low-density peripheral region and an oval central portion of lower density in the plain scan; the enhanced scan revealed a significantly enhanced peripheral region and a non-enhanced central portion. ¹⁸F-fluodeoxyglucose (FDG) positron emission tomography (PET)-CT showed a mass in the right hepatic lobe with an increased intake of FDG in the peripheral region (maximum standard uptake value, 5.7) and a non-increased intake of FDG in the central portion. The patient was then subjected to hysteroscopy and laparoscopy. Histopathologically, the mass was an ectopic pregnancy. The patient recovered following the surgery. In conclusion, a timely diagnosis of ectopic pregnancy was made for a 31-year-old women with an ectopic pregnancy in the liver on the basis of US, CT and PET-CT imaging results, which enabled surgery to be undertaken prior to any serious consequences. These observations may be helpful for the diagnosis of similar cases in the future.

Ectopic pregnancy not within the (distal) fallopian tube: etiology, diagnosis, and treatment

Ectopic pregnancy is a very common diagnosis (2% of pregnancies), and implantation location varies. Although 97% of ectopics are implanted within the fallopian tube, associated with commonly recognized risk factors, ectopic implantation can occur in other pelvic and abdominal locations that may not have such predisposing risk factors. After an extensive review of the literature, along with the author's personal experience, implantation frequency, etiologic possibilities, and treatment options for each ectopic pregnancy location are presented. When ectopic pregnancy is diagnosed early, before rupture, regardless of location, conservative, fertility-sparing treatment options can be successful in terminating the pregnancy. Predisposing risk factors and treatment options can vary and can be ectopic-location specific.

Secondary abdominal appendicular ectopic pregnancy

Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations. We present an interesting case of secondary implantation of a tubal ectopic pregnancy to highlight the appendix as a possible secondary implantation site after a tubal ectopic pregnancy.

Diagnosis and Management of Hepatic Ectopic Pregnancy

BACKGROUND

We present a case in which an adnexal mass caused symptoms that eventually lead to the identification of a primary hepatic pregnancy.

CASE

A young woman presented with abdominal pain, a positive hCG test result, an empty uterus, and a pelvic mass. Diagnostic laparoscopy revealed a cystic adnexal mass. An exploratory laparotomy with ovarian cystectomy identified a mature teratoma but no evidence of pregnancy in the pelvis. Because the patient's quantitative hCG level continued to increase without evidence of an intrauterine pregnancy, a dilation and curettage was performed which yielded no products of conception. An ultrasound examination and magnetic resonance imaging identified an 11-week ectopic pregnancy with fetal cardiac activity located in the maternal liver. This was treated with fetal injections of methotrexate and potassium chloride under ultrasound guidance and subsequent maternal intramuscular injection of methotrexate. The patient tolerated these interventions well, and subsequent ultrasound examinations showed absent fetal cardiac activity and decreasing fetal size. Serial hCG tests were followed up to zero, and the patient's liver enzyme levels remained normal.

CONCLUSION

With persistently rising hCG levels and no pregnancy identified in the uterus or pelvis, there should be a thorough evaluation of the entire pelvis and abdomen. Magnetic resonance imaging is a useful tool for locating such an ectopic pregnancy. Once identified, decisions regarding surgical versus medical management must take risk of adverse outcomes into consideration. This report reveals an 11-week hepatic pregnancy managed conservatively with fetal potassium chloride and maternal methotrexate administration.
