Interstitial ectopic pregnancy: A rare case report

Introduction: Interstitial pregnancies are a rare form of ectopic pregnancy with life threatening consequences. Thus, the aim of this report is to shed light on the importance of early diagnosis for optimal outcomes. Case presentation: Herein, we present a case of an interstitial ectopic pregnancy in a 31-year-old Syrian female who presented only with mild non-specific abdominal pain. The ultrasound showed a gestational sac in the right horn of the uterus non-communicating with the endometrial cavity suggesting an interstitial ectopic pregnancy. Cornual excision and salpingectomy were performed with laparotomy instead of laparoscopy due to resourcelimited facilities. Follow-up with serum human chorionic gonadotropin beta-HCG continued until the hormone levels became undetectable. Discussion: Interstitial ectopic pregnancies can present with non-classic symptoms. Ultrasonographic evaluation for lower abdominal pain in women at the first trimester is essential to detect interstitial ectopic pregnancies. Conclusion: Early diagnosis is key to prevent the life threatening progression of interstitial pregnancy, so this diagnosis should be kept in mind in women presenting with first trimester abdominal pain and/or vaginal bleeding.
