Multiple sclerosis – spinal cord atrophy

Multiple sclerosis – spinal cord atrophy. One of the imaging features of advanced multiple sclerosis is atrophy of the corpus callosum, illustrated in the sagittal T2-weighted image on the left here (arrows). Note the bright CSF. The patient also had multiple high-signal plaques in the cervical spinal cord, seen on the sagittal T2-weighted cervical spine image on the right. Note the focal area of thinning of the spinal cord (arrow), due to atrophy.
