BACKGROUND : Pelvic irradiation in childhood may result in abnormal uterine function. Poor obstetric outcomes have been reported in these patients. METHODS : A 30-year-old woman with a previous midtrimester miscarriage, G2, P0, presented at 234 weeks gestation with acute abdominal pain and signs of hemodynamic instability. The patient was treated in childhood for Ewing sarcoma of the pelvis. Spontaneous uterine rupture was diagnosed. A supracervical hysterectomy with intrauterine fetus was performed. CONCLUSIONS : A high index of suspicion is needed in primigravidas with risk factors for uterine rupture. Pelvic radiotherapy in childhood may be a risk factor.
