Female, 60 years old, with multiple sclerosis. Assess for progression. Given differences in imaging technique, there does not appear to be a substantial change in the size or number of T2 hyperintense lesions within the periventricular and juxtacortical white matter, and to a lesser extent the brainstem. As before, many of these lesions involve the corpus callosum or callososeptal interface and many are oriented radially with respect ventricles. Most correlate with moderate T1 hypointensity. No definite evidence of any new lesion is seen. Brain volume is preserved. No evidence of edema or mass effect is detected. Ventricular size and morphology remain within normal limits.
Numerous lesions are redemonstrated compatible with multiple sclerosis. No significant interval change in lesion size or number is suspected.
