MRI diagnosis of spontaneous uterine rupture of an unscarred uterus.

Spontaneous uterine rupture is a rare, potentially catastrophic complication of pregnancy, and its prompt diagnosis and treatment are essential in limiting morbidity and mortality. Clinical diagnosis is difficult and relies heavily on diagnostic imaging. Radiological diagnosis is also often difficult with most documented cases involving the use of ultrasound and computed tomography. Although magnetic resonance imaging (MRI) is being used more frequently to assess patients, there are few reports illustrating the utility of MRI and its advantages over other imaging modalities in the diagnosis of uterine rupture. This report documents a case of spontaneous uterine rupture diagnosed by MRI in a postpartum patient with an unscarred uterus.
