Abstract Objective The objective of this report is to describe a rare case of interstitial pregnancy ultimately resulting in a viable infant coexistent with massive perivillous fibrin deposition (MPFD). Study Design This study is a case report and literature review. Results A 35-year-old female patient underwent cesarean section at 32 weeks of gestation due to fetal growth restriction (FGR) and breech presentation. During the operation, a diagnosis of interstitial pregnancy was established. There was no evidence of placental separation. We decided to complete surgery without removal of the placenta and waited until the placenta delivered spontaneously. The conservative management was successful, and the patient was discharged on postoperative day 13. The pathologic examination showed MPFD. Conclusion If interstitial pregnancies are not diagnosed at an early gestational age, it can result in a viable fetus, but such pregnancies may be associated with FGR or placenta accreta.
