Figure 2. Magnetic resonance images on the day of seizure (A, B) and after 2 months (B, C). T2 flair image on the day after the seizure episode showing T2 hyperintensity without diffusion restriction in both caudate nucleus (arrows), putamen (arrows), right thalamus (arrows), pulvinar, and both middle cerebellar peduncles. Osmotic demyelination syndrome was suggested. (B) Diffuse T2 hyperintensity with mild diffusion restriction in right cerebral cortical area (arrows). Cortical signal change was predominantly in the insular temporal and parieto-occipital lobe. (C, D) After 2 months, follow-up MR showed that T2 hyperintensity was normalized (T2-weighted images).
