MRI
At the supratentorial level, left hemisphere asymmetry is observed. It is smaller than the right with cerebral atrophy, associated with thickening of the left frontal and parietal bone diploe, in addition to the prominence of the arachnoid space and central, superior temporal, insular, and parietooccipital sulci. Associated retraction of the left lateral ventricle is observed prominently in all its portions, with a gliosis zone at this level.
