Note: mo: months; d: days; y: years; w: weeks; r: right; l: left; EEG/PET: EEG monitored during FDG uptake; F: frontal; preF: prefrontal; med: medial; C: central; T: temporal; sup: superior; ant: anterior; P: parietal; O: occipital; Cing: cingulate; SUV: standardized uptake value; SUV ratio: average SUV of the hypermetabolic region/average SUV of homotopic contralateral region; Follow-up SUV ratio was calculated in the same region on follow-up PET scans of the patients. n.a.: not available; Letters in parenthesis indicate possible or mild involvement of the indicated lobe.

^*The digital format of the follow-up scan of patient #9 has been damaged; however, the printed copy shows hypometabolism in the area of initial hypermetabolism in addition to the posterior regions.
