Uterine rupture during pregnancy caused by uterine dysplasia, such as the double uterus, is very rare and easily overlooked by the surgeon. A 25-year-old woman, at 17 weeks of gestation presented to our emergency center with acute right lower abdominal pain for more than 10 h. The initial diagnosis is acute appendicitis, but during the exploration, we found about 2500 mL of intraperitoneal hemorrhage, appendix was normal, pregnancy in one of the double uterine and ruptured at the right bottom. The pregnancy was removed and the uterine defect was repaired. Uterine rupture caused by double uterus is very rare and easily Ignored by the surgeon.
