FLAIR images show hyperintense material that fills diffusely the sulci of both hemispheres, the sulci of the cerebellum and basal cisterns. Post-contrast images show diffuse leptomeningeal enhancement (better seen in post-contrast axial FLAIR images than post-contrast axial T1-SE images). T1-SE post-contrast images shows a DVA in left cerebellar hemisphere.
