A peripherally-based contrast-enhancing mass, involving the cortex and abutting the 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. It 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.
