- Figure 1
EEG features a) Interictal EEG showed normal EEG background of 8-9 hertz bilaterally (thin arrows). Intermixed slow transients of 6-7 hertz in the temporal regions bilaterally (thick arrows). No epileptiform discharges seen, b) The ictal EEG showed periods of right hemispheric electro-decremental response with right hemispheric alpha frequency attenuation at FP2, F4, T2, T4, T6, P4 & O2 with some diffusion to the left for 4 seconds time locked with left facio brachial tonic seizure (thick arrows) followed by recovery of the EEG background intermixed with right temporal slow transients of 4-5 hertz at T2, T4 and T6 (thin arrows).

MRI brain at presentation a) Axial apparent diffusion coefficient (ADC) map, b) Axial fluid attenuated inversion recovery (FLAIR) and c) Coronal T2 spin echo (T2SE) images showing abnormal high T2 and FLAIR signal intensity and swelling with blurring of the margins of right amygdala and medial right temporal lobe cortex and increased diffusivity associated on ADC map (White arrows). No abnormal enhancement (post contrast images not shown).

PET scan of the brain at presentation showed hypermetabolic right mesial temporal area (White & black arrow heads) which matched with MRI abnormality (White arrow).
- Figure 4
Neuroimaging at 7 months of treatment a) MRI brain axial ADC map, b) MRI brain axial FLAIR and c) MRI brain coronal T2SE showing almost complete resolution of the signal abnormality with no atrophic changes (white arrows). d-e) The PET scan of the brain showed interval resolution of the focal hypermetabolic activity previously seen in the right temporal lobe with ipsilateral relative mesial temporal and right basal ganglia hypometabolism (white arrows).
