Brain MRI of Case #1–3. Sagittal T2-weighted (upper row) and axial FLAIR (lower row) brain MRIs. Patient 1 (a and d) showed mild to moderate atrophy in the frontotemporal regions, minimally asymmetric, with right frontal encephalomalacia. Patient 2 (b and e) showed similar findings with somewhat lower burden of associated periventricular and spotty subcortical white matter increased signal. Patient 3 (c and f) showed mild diffuse atrophy with minimal periventricular and subcortical white matter disease
