Sagittal CT, sagittal T1WI/T2WI, and axial T1WI/T2WI MRI sequences show an expansible, well-circumscribed lesion in the posterior elements extending within the spinal canal, with severe spinal canal stenosis and compressed spinal cord (white arrow). Areas of low signal on T2W1 from hemosiderin are indicated by the red arrow.
