MRI of the head and spine (Figures 1-3) showed extensive basal intracranial meningeal thickening and enhancement extending along the spinal canal circumscribing the whole spinal cord down to the conus medullaris region (Figures 2, 3).
Sagittal tbl2WI and post-contract tbl2WI of the whole sping showing evident meningeal thickening and enchancement circumscribing the spinal cord and extending extensively along the cadua equina nerve roots almost completely replacing the CSF spaces and resulting in dry CSF puncutre.

Axial tbl2 WI and tbl1 WI of the lumbar spine at the level of L1 and L2 vertebrae showing significant meningeal thickening and dense enhancement along the surface of the conus medullaries region and the cauda equina nerve roots replacing the CSF space at these levels.
