Description of Ictal HFO Mapping in Patients with Both Temporal and Extratemporal Seizure Focus

Table 1

Clinical features, imaging correlation, and ictal HFO data.

#	Age/gender	Interictal EEG	Ictal EEG onset	3T-MRI	Aura	Semiology	Ictal HFO mapping
1	24 y/F	R-frontal and temporal spikes	R-temporal rhythmic theta	Normal	No	Confusion, late head turn to left and left arm posturing	Right anterior frontal and right mesial temporal
2	31 y/F	Left and right temporal spikes	R-orbitofrontal followed by bitemporal	Normal	No	Generalized tonic seizure without warning	Right orbitofrontal propagating to bilateral temporal lobes
3	39 y/F	Left temporal spikes	Left anterior temporal	Larger Left hippocampus	No	Staring	Left posterior orbitofrontal region with rapid propagation to mesial temporal and subsequent lateral temporal cortex
4	27 y/M	Left temporal spikes	Left anterior temporal	Normal	Metallic smell and vision distortion	Staring followed by GTC	Left mesial temporal with rapid propagation to the posterior orbitofrontal region and subsequent lateral temporal cortex
