Figure 1: A. FLAIR axial image shows asymmetrical hyperintense signal in the hippocampi (left > right). B. FLAIR image shows asymmetrical hyperintense signals in posterior temporal cortices with visible swelling of the cortical gyri and sulcal effacement. C–F. Axial DWI and apparent diffusion coefficient (ADC) maps at consecutive levels show hyperintense signal in the parieto-temporal cortices in DWI, with hypointensity predominantly seen in the subcortical white matter in these regions in corresponding ADC maps suggestive of diffusion restriction
