Coexisting ovarian and tubal pregnancies on opposite sides after intrauterine insemination: a case report

Abstract

Background: Ovarian pregnancy is very rare, and contralateral tubal pregnancy coexisting with ovarian pregnancy must be even rarer. Case presentation: A 33-year-old Korean nulliparous woman was referred to our hospital because she suffered lower abdominal pain and had missed her periods after controlled ovarian hyperstimulation and intrauterine insemination. We could not identify any normal gestational sac in the endometrium, or specific ectopic pregnancies, on an initial ultrasound scan. However, there was a large hematoma in the cul-de-sac and free fluid in the right paracolic gutter. We decided to perform emergent laparoscopic surgery. We found contralateral tubal and ovarian ectopic pregnancies. Conclusion: To the best of our knowledge, this is the first report of a case in which a patient underwent laparoscopic right salpingectomy and left ovarian ectopic mass excision due to contralateral tubal and ovarian ectopic pregnancies after assisted reproductive technology.
