Placenta Percreta With Spontaneous Rupture of an Unscarred Uterus in the Second Trimester

In Brief BACKGROUND Rupture of a pregnant uterus occurs most often in a scarred uterus, and spontaneous rupture of a non-scarred uterus in the early second trimester is rare. CASE A woman with two previous normal vaginal deliveries and no prior trauma to the uterus presented at 16 weeks' gestation with an acute abdomen due to intraperitoneal hemorrhage. A large rupture of the fundus of the uterus was found. A supracervical hysterectomy was carried out, with subsequent good recovery. The specimen showed placenta percreta. CONCLUSION Spontaneous rupture of an unscarred uterus, due to placenta percreta, should be considered in cases of acute intraperitoneal hemorrhage, even in early pregnancy. Spontaneous rupture of a non-scarred uterus in the second trimester of pregnancy due to placenta percreta is a very rare and potential life-threatening event.
