Background:
Laterally implanted pregnancies-including angular, interstitial, and cornual pregnancies-are rare and diagnostically challenging due to overlapping clinical and imaging features. They may mimic a normal intrauterine pregnancy but are associated with significant maternal morbidity. This case describes a prenatally undiagnosed suspected angular pregnancy complicated by placenta accreta spectrum (PAS).
Case:
A 39-year-old G1P0 woman underwent induction of labor at 37 weeks for fetal growth restriction and gestational hypertension. Postdelivery, retained placenta was noted. Intraoperative evaluation revealed placental tissue in the left cornua concerning for PAS. Placental removal was unsuccessful, and peripartum hysterectomy was performed.
Conclusion:
Laterally implanted pregnancies are rare and may be diagnosed only at delivery. Early recognition of abnormal implantation and multidisciplinary management are essential to reduce maternal morbidity.
