Figure 3: Follow-up imaging. Axial fluid-attenuated inversion recovery (a) images show confluent hyperintensities involving bilateral fronto-parietal lobes. Coronal T2-weighted image (b) shows involvement of the left temporal lobe, bilateral basal ganglia and external capsule. Diffusion weighted (DW) trace (c) and apparent diffusion coefficient (ADC) map (d) shows restricted diffusion in bilateral internal capsules, subcortical white matter of right frontal and bilateral occipital lobes. DW trace and ADC map (e and f) at higher level show confluent areas of restricted diffusion in bilateral centrum semiovale. Areas of increased ADC are noted in the right frontal lobe
