However, atrophy of the left frontal skin and calvaria is noted (arrow). B, The T2-weighted image shows a few hyperintense lesions in the right basal ganglia and right posterior periventricular white matter (arrow). The midbrain appears with mild atrophy on the right side (not shown). C and D, A 3D volume rendering image shows focal skin and calvarial atrophy (arrows) over the left frontoparietal and the right parieto-occipital regions.

A, The pyramidal tracts are clearly depicted on the left hemisphere but are sparse on the right hemisphere (arrows). B, The sensory tract on the right side is prominently involved (arrow).
