Figure 1 CT scan of the posterior spinal epidural hematoma was spindle-shaped high density, dural sac pressure forward. Figure 2 MRI sagittal T1 WI and T2 WI epidural hematoma spindles slightly shorter T1 mixed T2 signal, the spinal cord was significantly pressure forward. Figure 3 axial T1 WIGD DTPA enhanced hematoma significantly enhanced. Figure 4 sagittal T1 WIGD DTPA enhancement,
