Multiple sclerosis. Ataxia. The patchy and confluent periventricular cerebral white-matter T2-hyperintensity has not significantly changed since the previous examinations. Some of the lesions are also mildly to moderately T1-hypointense. The corpus callosum is involved by some lesions and is thinned, as part of the generalized brain volume loss. There are also a few lesions involving the brainstem and cerebellum. An area of linear and branching subcortical enhancement in the anterior paramedian right left frontal lobe is unchanged.
1. Extensive white matter lesions that are compatible with multiple sclerosis remain unchanged since May 2015. Associated moderate brain volume loss remain unchanged.2. A small enhancing subcortical lesion in the left anterior frontal lobe may represent a developmental venous anomaly rather than an enhancing demyelinating lesion.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
