Second Trimester Spontaneous Uterine Rupture in a Woman with Uterine Anomaly: A Case Report

Uterine rupture is a life-threatening obstetrical emergency carrying a high rate of mortality and morbidity for the mother and the fetus. Spontaneous uterine rupture usually occurs in scarred uterus in late pregnancy. Spontaneous unscarred uterine rupture in the early pregnancy is a rare complication and among them anomalies of the uterus are one of the causes. Here, we report a case of gravida 2, abortion 1, presented at 20 weeks of gestation with acute pain abdomen. Ultrasound abdomen showed a single macerated extrauterine fetus of 17 weeks in the abdominal cavity suggestive of the intra-abdominal pregnancy. Emergency laparotomy revealed a uterine anomaly with right horn rupture. Clinical signs of uterine rupture in early pregnancy are non-specific and must be distinguished from other acute abdominal emergencies.
