Placenta previa-percreta: magnetic resonance imaging findings and methotrexate therapy after hysterectomy.

A case is reported of a 42-year-old woman with placenta previa-percreta and multiple previous cesarean sections. Preoperative magnetic resonance imaging findings are described. Management included a cesarean supracervical hysterectomy, bilateral hypogastric arterial ligation, and intraoperative methotrexate administration. The placental portion that invaded the urinary bladder wall was left in place, without attempt to remove it surgically.
