Female, 14 years old, with autoimmune disease with new brain lesions, preoperative planning exam for brain biopsy. Multiple patchy ill-defined areas of parenchymal and brain surface enhancement are again seen involving the bilateral cerebral hemispheres and the cerebellum. These appear similar to the prior examination accounting for differences in technique. Several of the enhancing lesions, and particularly the dominant enhancing lesion in the right cerebellum, are associated with surrounding T2 hyperintensity. Also noted is an area of subcortical T2 hyperintensity and mild gyral volume loss without enhancement involving the left parietal lobe, again similar to prior.
Redemonstration of multiple cerebral and cerebellar lesions, most of which enhance, which appear similar to the immediate prior examination.
