    "abstract": "Ectopic pregnancy is the leading cause of pregnancy-related death during the first trimester. Bilateral ectopic pregnancy is a rare phenomenon, varying in frequency between 1 per 725 and 1 per 1,580 ectopic pregnancies. We report the case of a bilateral ectopic pregnancy (ruptured right cornual and intact left ampullary) in a patient with no known risk factors for extrauterine gestation.\nA 33-year-old, black woman, gravida 2, para 1001, presented at approximately 7 weeks' gestation with the acute onset of abdominal pain. She had a rigid surgical abdomen but was hemodynamically stable. Her beta-human chorionic gonadotropin level was 6,398 mIU/mL, and transvaginal ultrasound failed to reveal an intrauterine gestation, adnexal mass or cul-de-sac fluid. Findings at laparotomy included a 500-mL hemoperitoneum and a ruptured right cornual and intact left ampullary pregnancy. Pathology of both specimens confirmed the presence of chorionic villi.\nAlthough rare, heterotopic pregnancies can occur even in patients without risk factors.",
