title: Heterotopic pregnancy: case report.
abstract: Heterotopic pregnancy in a spontaneous cycle is a rare entity with an estimated frequency below one per 30,000 pregnancies. Its incidence evidently has increased in accordance with the widespread use of in vitro fertilization and ovulation induction. We report a case of heterotopic pregnancy in a 40-year-old woman who presented with acute abdominal pain. We also present findings from transvaginal ultrasound imaging.
