Video-EEG monitoring recorded focal motor seizures, as previously described, with spike and polyspike discharges within theta activity starting from the left temporal regions and spreading to frontal ones bilaterally (Fig. 1).
Brain magnetic resonance images (T2/FLAIR sequences). a,b) Coronal images showing hyperintense areas of altered signal in left fronto-parietal regions and left thalamus. c) Axial image showing hyperintense pathological areas in left fronto-parietal regions. FLAIR = Fluid attenuated inversion recovery.

After four days brain MRI with c.e. was repeated, showing T2/FLAIR (fluid attenuated inversion recovery) hyperintense areas of altered signal without c.e. in the left thalamus and homolateral cortical and sub-cortical fronto-parietal regions (Fig. 2).
