Advanced ovarian pregnancy is a quite rare condition. Due to the high maternal and neonatal mortality rates, early and accurate diagnosis is vital. Lack of sufficient data led us to search the literature and compile available data on the topic. A 33-year-old woman presented with acute abdomen at 34 weeks of gestation. She underwent laparotomy, which revealed a live foetus surrounded by an intact amnion membrane located in the left adnexal area. The patient delivered a live female infant. Heavy bleeding from the placenta necessitated salpingo oophorectomy. Histological examination of the removed tissue confirmed the ovarian pregnancy. Because of the substantial risk of adverse outcomes, this condition should be borne in mind, especially in cases presenting with acute abdomen during pregnancy.
