Summary
A rare case of heterotopic pregnancy was diagnosed late at 13 weeks gestation. This occurred in a patient with an ongoing intrauterine pregnancy following assisted reproductive technology, highlighting diagnostic challenges.
Area of Science:
- Reproductive Endocrinology
- Obstetrics & Gynecology
Background:
- Ovarian hyper-stimulation syndrome (OHSS) can present with abdominal pain and distension in early pregnancy.
- Adnexal masses in early pregnancy require careful evaluation to differentiate from other pathologies.
Purpose of the Study:
- To report a challenging case of heterotopic pregnancy.
- To emphasize the diagnostic difficulties in differentiating OHSS, pelvic infection, and ectopic pregnancy.
Main Methods:
- Case report of a 26-year-old female undergoing assisted reproductive technology.
- Clinical evaluation, serial pelvic ultrasounds, and diagnostic laparotomy.
Main Results:
- Initial diagnosis of OHSS and pelvic infection due to left adnexal mass.
- Delayed diagnosis of right-sided ectopic pregnancy at 13 weeks gestation via laparotomy.
- Successful salpingostomy performed, with ongoing intrauterine pregnancy.
Conclusions:
- Heterotopic pregnancy can mimic other conditions like OHSS and pelvic infection.
- High index of suspicion and advanced imaging may be needed for early diagnosis.
- Timely intervention is crucial for managing heterotopic pregnancies to preserve intrauterine gestation.
