The lumbar vertebral column is normally aligned and there is no pathologic marrow signal intensity or fracture. Intervertebral disc space height and signal intensity is normal and the endplates are intact.

The conus medullaris terminates normally at lower L1.

On the T2 weighted sequences there is possible thickening and definite clumping of the nerve roots of the cauda equina within the thecal sac. No extradural abnormalities are noted. There is no compression of the thecal sac or nerve root sheaths at any level.

Post-contrast imaging shows diffuse enhancement within the thecal sac from the conus medullaris distally without definite focal or nodular enhancement. The abnormal enhancement includes the nerve roots and nerve root sheaths from L3/4 distally on both sides.
