Multiple sclerosis [G35], Reason for Study: ^Reason: MS; f/u progression History: paresthesias. There are multifocal various sized high signal intensity lesions on bilateral periventricular periventricular and deep white matter on FLAIR images. The lesion locations include right cerebral peduncle, right midbrain especially periaqueductal gray matter and median raphe, upper pons, left middle cerebellar peduncle as well as bilateral cerebellar hemispheres. Comparing to prior scan, overall number and location of these lesions do not show any significant interval change.The ventricles, sulci and cisterns are symmetric and unremarkable. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Multifocal high FLAIR high signal intensity lesions involving bilateral hemispheres, brain stem and bilateral cerebellar hemispheres which do not show any significant interval change in terms of number of lesions and size of each lesions since prior scan.
