FIG 2.

MR images from case 2 — tranverse T1WI before and after gadolinium administration, T2WI and FLAIR. The images reveal an intra-axial lesion in the right frontoparietal lobe, with an isointense core surrounded by hypointense margins on T1WI, hyperintense on T2WI and on FLAIR, with marked contrast enhancement on T1WI. The mass is surrounded by a diffuse perilesional oedema which contributes to the mass effect on the brain parenchyma, causing a subfalcine brain herniation and midline shift. The muscles and subcutaneous tissue over the visible skull lesion are hyperintense on T2WI and show diffuse contrast uptake on T1WI
