 Moderately extensive periventricular and subcortical white matter FLAIR lesions compatible with demyelinating disease. Prominence of the ventricles and sulci likely due to volume loss. There are no enhancing lesions or other findings to suggest acute demyelination. The cisterns remain patent. There is no midline shift or mass effect. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
Evidence of demyelinating disease with no enhancing lesions to suggest active demyelination.
