PRIMARY TWIN OVARIAN PREGNANCY

A 20-year-old-woman, gravida II, para I, was admitted to the hospital with vaginal bleeding 17 weeks after her last menstrual period. Her pe lvic examination was found to be compatible with 3.5 months of pregnan cy by the attending physician. Ultrasonographic examination revealed a n empty uterus and two dead fetuses with biometric data consistent wit h 14 weeks of pregnancy located in the left ovarian region. She was su bjected to an explorative laparotomy and an intact gestational sac inc luding the left ovary with normal tubes was observed; a unilateral sal pingo-oophorectomy was carried out. Histologic studies confirmed a twi n ovarian pregnancy. Although rare, ovarian pregnancy should be consid ered when approaching a case of ectopic pregnancy. Early diagnosis is generally based on ultrasonographic findings. Advanced cases with unru ptured sac and multiple gestations may also be present.
