- multiple bilateral supra- and infra-tentorial predominantly extra-axial as well as intra-axial small ring enhancing lesions are seen within the subarachnoid spaces of the cerebral and cerebellar convexities; with the largest in the right posterior high frontal parafalcine region is seen measuring 12 X 8 mm. Those lesions seen within the left sylvian fissure shows typical nodular branching with grape-like or racemose pattern. These lesions are associated with mild focal meningeal enhancement. They show predominantly low T1 and T2 as well as GRE/ SWI signal intensities with no restricted diffusion. They are associated with mild vasogenic brain edema.
- Mild supra and infra-tentorial hydrocephalic changes with mild peri-ventricular T2/FLAIR hyperintensity.
