Figure 1 T2 weighted MRI scans showing diffuse hyperintense signal abnormalities with prominent involvement of both temporal lobes (A), both thalami, external and extreme capsules (B), as well as widespread areas of the white matter (C). Diffusion weighted imaging does not show evidence of an acute ischaemic strokes but demonstrates a weak and diffuse signal alteration in the right parieto‐occipital cortex 24 h before the first EEG (arrow; D).
