Patient demographics.  Age and epilepsy duration are reported in years at the time of the scan.  Lesion resections are reported as yes (Y) if they were thought to be complete lesionectomies at the time of surgery; resections were partial (part) if they were limited by overlap with functional cortex.  Seizure outcome is reported as Engel Class at 12 months.  Transmantle signs were listed if no pathological evaluation was available, as these are thought to be present primarily in FCD type IIb lesions.  Lesion lobe abbreviations: R=right, L=left, F=frontal, C=central, P=parietal, T=temporal. *patients who did not undergo resection (Pt 8) or sufficient pathologic examination of the tissue of interest (Pt 9) but were found to have electrographic correlate with the relevant imaging finding on invasive EEG recordings.
