Intra axial left cerebellar mass is T1 hypointense, T2 hyperintense with central foci of cystic change and demonstrates homogeneous enhancement. Moderate amount of surrounding FLAIR hyperintensity but no significant mass-effect with pain in fourth ventricle and no hydrocephalus. The enhancing components demonstrate homogeneous diffusion restriction (ADC 560).
Suggestion of a tiny focus of leptomeningeal enhancement of the adjacent posterior vermis. No susceptibility artefact on SWI. No other mass lesion is identified.
Minimally increased CBV within the centre of the mass.
