Gestación heterotópica en un embarazo espontáneo

Heterotopic pregnancy consists of simultaneous intra and extrauterine pregnancy. The incidence is low in spontaneous pregnancies, but these pregnancies are more common when assisted reproductive technologies are used; therefore, diagnosis requires a high index of suspicion. We report the case of a 34-year-old woman with no history of interest and a spontaneous pregnancy, who presented with spotting and hypogastralgia. An ultrasound scan showed an intrauterine gestational sac and left adnexal mass consistent with ectopic pregnancy. As a heterotopic pregnancy was suspected, laparoscopic salpingectomy and curettage of the miscarriage were performed. Pathological analysis confirmed the diagnosis.
