case_images: A reconstructed axial three-dimensional fluid-attenuated inversion recovery image obtained from the patient with left-hemispheric Rasmussen encephalitis before surgery shows atrophy in the left hemisphere indicated by 'L' (repetition time: 4800 ms, echo time: 270.9 ms, slice thickness: 1.0 mm, matrix size 512 x 512).

case_images: FLAIR images (Figure 1) verified left-hemispheric atrophy in the frontal regions (co-authors: MT, SC, and SK). Further, in agreement with the observation that stage 4 encephalitis occurs approximately 8 years after seizure onset and leads to hemispheric atrophy, the brain regional volume in our patient, who had experienced seizures for 15 years, showed that the left anterior frontotemporal region was the most affected area (volume of atrophy/damage: 15.13 cm3, mean +- standard deviation: 248.05 +- 126.34).
