Left & middle: sagittal T2WI's show an oval heterogeneous but relatively
hypointense mass in the posterior spinal canal of the lower thoracic spine.
It causes severe stenosis of the central canal and compresses the spinal
cord. Severe degenerative changes with vertebral body height loss and
disc desiccation are present.
Right: This mass is predominantly isointense on T1WI.
Left: T1WI again shows the central canal stenosis.
Right top & bottom: axial T2WI's show that the heterogeneous mass is
extra-dural and displaces the thecal sac and spinal cord anteriorly.
