Female, 41 years old, with paresthesias and history of multiple sclerosis. Evaluate for progression. Extensive periventricular and scattered juxtacortical T2 hyperintense lesions are redemonstrated, most of which show correlating moderate to marked T1 hypointensity. Lesions are also noted on both sides of the pons and in the right cerebellar hemisphere. On comparison with the prior examination, there has been no significant interval change in the size and distribution of these lesions, nor in their T1 or T2 signal characteristics. No new lesions are appreciated. Moderate generalized cerebral volume loss is seen. No other significant findings are noted.
Scattered lesions are demonstrated both supra- and infratentorially compatible with multiple sclerosis. There has been no significant interval change in the size, number, or signal characteristics of these lesions.
