Interstitial ectopic pregnancy: A rare case report

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.

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 resource-limited facilities. Follow-up with serum human chorionic gonadotropin β-HCG continued until the hormone levels became undetectable.

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.

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.
