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.
