Rounded relatively symmetrical capsulo-lenticular masses isointense to the cortical grey matter on T1, FLAIR and T2 with restricted diffusion on DWI/ADC. Surrounding vasogenic oedema of a low signal on DWI and facilitated diffusion on ADC. No haemorrhagic component on the GE sequence. The postcontrast sequence shows a vivid homogeneous enhancement.
The MR spectroscopy shows an intratumoural choline peak, lipid peak (tumour necrosis) and depleted NAA.
Two other small enhancing nodules are noted in the right temporal and left frontal lobes at the grey-white matter junction..
Trichilemmal cysts are noted.
