Multiple sclerosis, paresthesias. Evaluate for 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 3/19/2014, there is no definite evidence of new lesions. There is possible T2/flair hyperintense lesion involving the right superior cerebellar vermis which is favored to be artifact, axial FLAIR 27/78, and was not seen on prior. Left callosal body lesion is decreased in size in the interval. Juxtacortical lesion involving the left precentral gyrus again seen. Few T1 hypointense lesions such as in the left superior parietal lobule are again seen. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Brain parenchyma volume appears within normal limits. Major flow-voids are preserved. Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
No new demyelinating lesions are definitively appreciated to suggest disease progression.
