Mass lesion predominantly T1 isointense to white matter, with focal hypointense areas. Adjacent white matter T1 hypointensity.
On T2 there are areas of marked hypointensity and small areas of hyperintensity, with marked vasogenic oedema. The lesion appears cortically-based, and is heterogeneous on FLAIR, with foci of marked hypointensity.
b1000 images suggest some marginal diffusion restriction. ADC confirms some minimal marginal diffusion restriction.
Postcontrast images show prominent enhancement, with a few small areas of non-enhancement. The enhanced lesion is well defined.
