Lumbar Spinal Stenosis: Spondylolithesis

A 72 year-old man noted chronic low back pain, worst with standing and walking.

Compare the Thecal Sac Above and At the Spondylolithesis

(Left) Axial T2-weighted MRI at L3; (Right) Axial T2-weighted MRI at the L4-5 disk level. Note the severe stenosis at the L4-L5 level with the complete absence of CSF. Contrast this to a normal level above at the L3 level and the normal amount of CSF surrounding the descending nerve roots of the cauda equina.
