Pat # | Age | Gender | Hand | rs_Mean Localiz. | NM Std. Localiz. | ED Mm | Comments |
29 | 6 | F | LH | L-temporal | L-parietal | 67.1 | Dx: Cortical Dysplasia. Interictal EEG showed left posterior quadrant discharges. PET showed complete left hemisphere hypometabolism. Was not operated. |
28 | 17 | F | RH | L-temporal | L-parietal | 68.0 | Dx: Viral Encephalitis. Interictal EEG with left parietal (P3) spikes. PET showed left central and left temporal hypometabolism. Was not operated. |
8 | 11 | M | RH | L-temporal | R-temporal | 76.0 | Dx: Cortical Dysplasia. Interictal EEG showed independent bilateral temporal dischargers. Left ones were rare. Patient had right temporal lobectomy. Asymptomatic since then. |
10 | 10 | F | RH | L-frontal R-mesial- occipital | R-temporal R-mesial- occipital | 96.1 | Dx: Cortical Dysplasia. Two rs-Mean ROIs were found. The largest ROI was chosen for comparison. Interictal EEG showed right temporo-occipital discharges. EEG-source localization showed right-mesial occipital dipole in one solution and the right inferior posterior temporal in a second solution. Ictal EEG showed right centro-parietal discharges. rs-Mean showed evident low signal in the right parietal area. |
11 | 15 | F | LH | L-temporal | R-temporo- parietal | 93.3 | Dx: Non lesional. Ictal EEG showed right temporal onset. rs-Mean has clear low values in the right temporo-parietal area. Seizure-to-rs-fMRI interval was more than 72 hours. |
21 | 8 | M | RH | L-temporal | L-temporal | 82.0 | Dx: Non lesional. Ictal EEG showed right frontal onset. The rs-Mean showed evident low signal area in the right frontal lobe. Seizure-to-rs-fMRI interval was 1 hour. The patient underwent right frontal resection. Has remained seizure free for more than 12 months. |
20 | 4 | F | RH | R-occipital | R-frontal | 71.5 | Dx: Tuberous Sclerosis. Ictal EEG showed right frontal onset in majority of registries, but one episode was documented with “convincing right occipital onset”. The rs-Mean had clear areas of very low intensities in both frontal lobes (right more than left). Seizure-to-rs-fMRI interval was more than 72 hours. Patient was not operated. |
26 | 11 | 1M | RH | L-occipital | R-temporal | 96.0 | Dx: Tuberous Sclerosis. Ictal and interictal EEG showed bilateral independent focus in posterior quadrants. Both SPECT and rs-Mean showed more than one area of hyper intensity. Comparison was performed between more conspicuous areas. rs-Mean showed in addition to the left-occipital, left frontal, right parietal. SPECT findings were subtle. Clinically, the patient had seizures with right eye and head version to the right. The patient was not operated. |
