Figure 1.
Figure 1. Sagittal post-contrast T1-weighted image of the thoracic spine reveals a lesion in the posterior (increased signal intensity) epidural region compressing the cord (a). Sagittal T2-weighted image of the thoracic spine at the same level depicts the same lesion in the posterior epidural region with low signal intensity (b).
