Brain magnetic resonance imaging and electroencephalography findings of Patient 2. Magnetic resonance image (A: diffusion-weighted imaging, B: fluid-attenuated inversion recovery imaging) obtained in the acute phase shows high-intensity lesions in the medial thalamus (arrows). Electroencephalogram obtained in the acute phase shows generalized periodic discharges with polyspikes (C). The findings of Patient 2 are similar to those of Patient 1, and they improved in the chronic phase (D-F)
