Gestación heterotópica triple: gestación gemelar intrauterina

Heterotopic pregnancy is increasingly common in Spain mainly due to the greater use of in vitro fertilization techniques. We report a case of heterotopic pregnancy after artificial insemination in a patient who consulted for mild metrorrhagia. Ultrasound examination showed a diamniotic dichorionic twin pregnancy and a singleton intrauterine gestation in the right tube. The case was resolved by laparoscopic unilateral salpingectomy. The symptoms of these rare pregnancies are nonspecific. Moreover, they are usually underdiagnosed, because the adnexa are not usually examined when an intrauterine gestational sac is found. Due to the severity of maternal and fetal compications, early diagnosis is essential.
