FLAIR images of MRI (A) at onset, (B) one month after onset (seizure frequency was 10 per day), (C) three months after onset (seizure-free), and (D) one year after onset (continuously seizure-free).

Examinations conducted using echocardiography, Holter electrocardiography, and brain MRI (Fig. 1A) revealed no abnormality. Fluid-attenuated inversion recovery (FLAIR) images of brain MRI showed high intensity in the right hippocampus, right uncus, right amygdala, and swollen right hippocampus (Fig. 1B). Two months after the cessation of seizures, the lesion indicated by the high intensity of the FLAIR images on MRI was improved (Fig. 1C). However, one year after, his right hippocampus was revealed to be atrophic on MRI (Fig. 1D).
Electroencephalography displayed with a monopolar montage in the 10-20 system. Rhythmic discharge was apparent in the right temporal area (F8, T4, T6). Onset of ictal discharge was clinically associated with cold shivers and piloerection.
