Herniation of the amniotic sac into the peritoneal cavity or bladder is a rare but serious condition during pregnancy, which has not been reported in pored congenital uterine anomaly. Here, we report a rare case to draw obstetricians’ attention to the atypical uterine rupture. A primigravida at 35 weeks of gestation was admitted for upper abdominal pain. A primary diagnosis of uterine rupture was made after finding the amniotic sac herniation through obstetric ultrasound. Exploration during emergent cesarean section revealed symmetrical pored defect on the uterine horn. The diagnosis of uterine anomaly was eventually made. The educational meaning of this rare case is that it is advisable to rule out uterine anomalies when signs of uterine rupture are suspected during pregnancy while contributory risk factors have not been identified. Besides, it is of vital importance to make a full assessment of both the mother and the fetus so to determine the appropriate time of termination.
