(A) Sharp waves, left fronto-central. (B) EEG seizure pattern, left fronto-central.
Small focus of abnormal signal in the left frontal periventricular white matter.
(A) Sharp waves, F8 Sp2. (B) EEG seizure onset. (C) EEG seizure evolution (1 minute from onset). EEG seizure pattern, right temporal.
Axial and coronal FLAIR MR. High signal in the right anterior insula consistent with a cortical dysplasia.
Case 3. EEG seizure pattern, generalized. Diffuse suppression followed by generalized rhythmic delta maximum over frontal and central regions.
