Paresthesias, evaluate for multiple sclerosis progression.. There are greater than 10 foci of T2/flair hyperintensity in the bilateral periventricular and subcortical white matter with appearance and distribution compatible with known demyelinating disease. Compared to 3/18/2015, there are no new lesions. Juxtacortical lesion involving the left precentral gyrus again seen. Minimal T1 hypointense lesions such as in the left superior parietal lobule are again seen. Brain parenchymal volume is preserved. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Calvarium and extracranial soft tissues are grossly unremarkable.
No new demyelinating lesions to suggest disease progression.
