Female, 30 years old, with multiple sclerosis. Assess for progression. Again seen are numerous periventricular and subcortical T2 hyperintense white matter lesions. Some of the periventricular lesions are relatively focal and oriented perpendicularly with respect to the ventricles while in other areas the abnormality is ill-defined and confluent. Disease is also seen within the corpus callosum and to a lesser degree in the middle cerebellar peduncles and brainstem. Accounting for differences in technique with the prior examination, there has been no significant interval change in size or number of these lesions.No evidence of parenchymal edema or mass effect is seen. The corpus callosum is thinned and the lateral ventricles are slightly prominent compatible with white matter loss. No abnormal extra-axial fluid collections are detected.
Stable white matter disease compatible with the history of multiple sclerosis.
