A 40-year-old woman presented with severe vaginal bleeding. Initial workup with an abdominal sonography revealed endometrium for about 3 mm and free fluid in the abdomen. Hemodynamic instability with abdominal pain and free fluid in the abdomen prompted blood transfusion and laparotomy. There were about 1000 cc blood and clots in the abdomen at laparotomy. There was a longitudinal rupture from fundus up to cervix at the left side of the uterus. Tearing was in full thickness from serosa to endometrium. Scar of previous cesarean was transvers and not associated with this tearing. There was not any myomectomy scar.
