Ovarian apoplexy resulting from ruptured heterotopic pregnancy following intrauterine insemination.

Heterotopic pregnancy is on the rise with the use of assisted conception and commonly involves the fallopian tube. Ovarian heterotopic pregnancy is rare, with fewer than 40 reported cases in PubMed/Medline; cases of ovarian ectopic pregnancy after intrauterine insemination are even rarer, with only seven published reports. We report here a case of ovarian heterotopic pregnancy following intrauterine insemination; this could possibly be the first such report. Our patient presented with circulatory collapse in the first trimester and laparoscopy disclosed an ovarian pregnancy with hemoperitoneum. Following resection of the ovarian pregnancy, the intrauterine gestation continued undisturbed and the patient delivered at term. Heterotopic pregnancy and unusual ectopic locations should be considered a possibility in pregnant women with pelvic pain, particularly following fertility treatment, including ovarian stimulation and intrauterine insemination.
