Multiloculated right temporo-occipital intra-axial mass with mixed cystic and solid components. The cystic component is of low signal on T1WI and FLAIR and high signal on T2WI with no restricted diffusion. The solid component is isointense to the cortical grey matter on both T1WI and T2WI, as well as on FLAIR and DWI, with low ADC values and enhancement on postcontrast sequences. Moderate surrounding vasogenic oedema with hemispheric cortical swelling. Mass effect on the ipsilateral trigone.
The MR spectroscopy shows a choline peak with a high choline:NAA ratio.
