Supratentorial and infratentorial, extra-axial masses located at the level of the temporal horn of the right lateral ventricle, prepontine cistern and pontocerebellar angle, as well as in straight gyrus region, which are irregular in morphology, lobulated edges, hypointense on T1, isointense to the gray matter on T2 and FLAIR, with diffusion restriction and areas of susceptibility artifact on gradient echo sequence. After gadolinium administration, they present ring enhancement with hypointense central areas. As well as patchy and leptomeningeal enhancement with discrete perilesional vasogenic edema.
