Multiple sclerosis.Question: MS, follow-up progression. Signs and symptoms: Paresthesias. There is redemonstration of several scattered cerebral T2 hyperintense lesions mostly in the periventricular and subcortical white matter, callosal septal interface, pons, left inferior cerebellar peduncle and right superior cerebellar hemisphere. There are 2 new small T2 hyperintense foci in the right parietal subcortical white matter. Several of this lesions demonstrate corresponding T1 hypointensity. There is no evidence of intracranial hemorrhage, mass or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
Multiple scattered T2 hyperintense lesions predominantly in the bilateral cerebral periventricular and subcortical white matter as well as callosal septal interface suggestive of demyelinating disease with 2 small new foci in the right parietal subcortical white matter.
