Survival of the cornual pregnancy in a heterotopic gestation after in vitro fertilization and embryo transfer.

We present a case of combined intrauterine and cornual (interstitial) pregnancy after IVF-ET, with survival of the infant after the cornual pregnancy. The diagnosis of this rare phenomenon is difficult; a high index of suspicion and frequently ultrasound monitoring may enable early diagnosis in other forms of heterotopic pregnancy. Although the benefits of IVF-ET far outweight the risks of ectopic pregnancy, it is imperative that physicians who care for these patients be fully aware of the possibility of such a complication in this high-risk population.
