Background: Uterus Didelphys “double uterus” is a congenital malformation that results from complete failure of fusion of the ipislateral paramesonephric ducts during embryonic development. Ideally, diagnosis should be made before pregnancy and labor to prevent adverse outcomes. Case report: Miss OE was a 32-year-old Gravida2 Para0+1 social mother. She was referred to Enugu State University Teaching Hospital (ESUTH) at 41weeks+ 6 days gestation for prolonged term premature rupture of membranes (PROM) and intrauterine fetal death. A longitudinal vaginal septum and two vaginas were later found during a critical review for failed induction of labor, and uterus Didelphys was confirmed at an emergency caesarean delivery. A macerated 3.2 kg male baby was delivered from the gravid uterus. Postoperative recovery of the mother was uneventful. Conclusion: Clinicians should have high index of suspicion of uterine anomaly when assessing cases of dysfunctional labor to avoid delayed diagnosis and the associated adverse outcome.
