A contrast-enhancing mass is peripherally based, involving cortex and abutting dura which is smoothly thickened. Mild diffusion restriction has developed at the medial margin of the mass. The mass demonstrates elevated cerebral blood volume.
On spectroscopy, a voxel anterior to the contrast enhancement demonstrates elevated choline to creatine and increased lactate. There is increased local mass effect however no midline shift.
Additionally a right parietal parafalcine extra-axial, vividly enhancing mass is stable. This invades the superior sagittal sinus and extends into an overlying diploic space.
Elsewhere, scattered foci of FLAIR hyperintensity are in keeping with chronic small vessel ischaemia.
