Primary Ovarian Monochorionic Twin Ectopic Pregnancy A Case Report

BACKROUND: Primary ovarian pregnancy is a rare form of ectopic gestation and one that is often diagnosed only at the time of surgery. CASE: A 17-year-old primigravid woman presented to our clinic with lower abdominal pain, vaginal bleeding, and missed period. Transvaginal sonography revealed an empty uterus, normal-looking right fallopian tubes, and the presence of a gestational sac containing 2 yolk sacs and 2 embryos with cardiac activity on the right ovary. Methotrexate therapy failed and the patient was successfully treated with laparoscopic enucleation of the ectopic pregnancy mass. CONCLUSION: Surgery is the primary treatment modality of choice in twin ovarian pregnancy. Therefore, the differential diagnosis of ovarian pregnancy is of great importance in order to plan immediate surgery and save the patient from unnecessary medical treatment, and thus preserving future fertility.
