14 year-old female with headaches. Reevaluate known inflammatory brain lesions following immunosuppressive treatment. Multiple patchy ill-defined areas of parenchymal and brain surface T2/FLAIR hyperintensity and enhancement are again seen involving the bilateral cerebral hemispheres and the cerebellum. Overall, these lesions appear improved especially within the right cerebellum. There is residual persistent enhancement of a subset of these lesions, although this also has improved compared to the prior exam. There are no new lesions. There is evidence of a small biopsy tract in the left frontal lobe lesion without complication. The area of subcortical T2 hyperintensity and mild gyral volume loss without enhancement involving the left parietal lobe is again seen and remains similar to the prior exam. Redemonstrated is sinus inflammation which appears similar to the previous exam.
Persistent multiple cerebral and cerebellar lesions which are overall decreased in their T2/FLAIR conspicuity and enhancement, especially within the right cerebellum.
