A True Cornual (Interstitial) Pregnancy Resulting in a Viable Fetus

In Brief BACKGROUND: Interstitial ectopic pregnancies are known for their dangerous implantation location and high risk of rupture. CASE: We report an interstitial pregnancy that was not ruptured at the time of cesarean delivery. Hysterectomy was not necessary and a viable fetus was delivered with a neonatal intensive care unit stay compatible to any neonate of his gestational age. CONCLUSION: In very rare circumstances, interstitial pregnancies can result in a viable fetus, and careful inspection of second-trimester ultrasonogram can lead to proper management of complicated ectopic pregnancies. Interstitial ectopic pregnancies carry a high risk of rupture, but, in rare circumstances, can produce a viable fetus.
