(A) Diffusion-weighted MRI (DWI) showing gyriform hyperintensity bilaterally in frontal, parietal, temporal, and occipital lobes, with the hyperintensity being more prominent on the right side. (B) Fluid-attenuated inversion recovery (FLAIR) image showing hyperintensity in the right parietal and temporal cortex.

The brain MRI showed gyriform hyperintensity bilaterally in the frontal, parietal, temporal, and occipital lobes, with the hyperintensity being more prominent on the right side in DWI (Fig. 1).
(A) Ictal EEG showing rhythmic discharges arising from the right hemisphere, and (B) then spreading to the contralateral hemisphere. (C) Interictal EEG showing right-sided lateralized periodic discharges (LPDs) with maximum amplitude in the right mid-frontal region. (D) Follow-up EEG nine days later showed periodic sharp wave complexes (PSWC) with right predominance and recurrence every 0.8-1.2 s.

An ictal EEG showed rhythmic epileptiform discharges arising from the right hemisphere and then spreading to the contralateral hemisphere (Fig. 2A, B). An interictal EEG showed right-sided lateralized periodic discharges (LPDs) with maximum amplitude in the right mid-frontal region (Fig. 2C). The follow-up EEG nine days later showed PSWC with right predominance and recurrence every 0.8-1.2 s (Fig. 2D).
