Fig 1.

A, The T1-weighted image (at the level of basal ganglia) shows no abnormal lesion in the brain. 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.
