Altered signal areas are se in the bilateral fronto-parietal and perisylvian cortical-subcortical region, which shows subtle restricted diffusion seen on DWI. After administration of contrast, there is gyriform enhancement seen in the bilateral fronto-parietal, perisylvian region and left temporal region.
Multiple small subcentimeter size nodular and ring enhancing lesions are seen in both cerebellum, midbrain and bilateral parieto-occipital region.
There is an exaggerated enhancement of the meninges seen at basal cistern and along the cortical sulci.
Mild dilatation of both the lateral and third ventricles.
