Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) scans at emergency department (ED). Sagittal, A, and coronal, B, CT images show high-density fluid retention in the uterus from the top of the vaginal canal (arrow). High-density fluid is also observed in the abdominal cavity on both sides of the uterus (arrowhead). C, Sagittal MRI (T2-weighted image) shows blood retention from the cervix to the upper vaginal area (arrow), but the retention cavity does not extend to the perineum (arrowhead).
