In the posterior fossa, an intra-axial lesion of rounded morphology is identified within the right cerebellar hemisphere, with defined edges and heterogeneous, thin septa in its anterior portion. It is cystic, predominantly hypointense in T1 and hyperintense in T2 with suppression in FLAIR, without restriction to diffusion or artifact on susceptibility-weighted imaging. It has mass effect displacing the vermis and left cerebellar hemiphere towards the left with partial compression of the fourth ventricle but without hydrocephalus.
In addition, it has bone remodelling in the right occipital region.
