Spinal cord compression in a patient with mucopolysaccharidosis type I (MPS I, Hurler-Scheie syndrome) A

A sagittal T2-weighted magnetic resonance image of the spine in a 25 year old with Hurler-Scheie syndrome and spinal cord compression, making him unable to walk. Little or no CSF (white) is anterior to the cord (gray) in the thoracic and cervical region. In the upper cervical region, CSF is completely excluded by meningeal thickening, which also compresses the cord.
