case_images: In addition, there was a focal subcortical heterotopy of the right cerebellar hemisphere, as shown in Figure 2.We conducted a prolonged 24-h video-EEG monitoring with drug withdrawal [Figures 3 and 4].
case_images: Scalp electroencephalography (EEG), 12 sec EEG page, longitudinal bipolar montage, passband of 0, 5-70 Hz with a gain of 10 micro V/mm. The results showed a run of left parieto-temporal spike-polyspike discharges.

case_images: Invasive electroencephalography (EEG), 12 sec intracranial EEG page (noisy and isoelectric channels excluded for clarity), bipolar montage, passband of 0, 3-150 Hz with a gain of 30 microV/ mm. Interictal synchronous spikes in the Occipital -heterotopia posterior (O-Ht post), Occipital -heterotopia inferior (O-Ht inf) electrodes as well as in the T1 electrode were observed.

case_images: A fusion of magnetic resonance imaging and computed tomography scans of the patient who underwent implantation of depth electrodes. The planned trajectories for electrode placement are represented by colored straight lines. In addition, one of the implanted electrodes is visible and indicated by the red arrow. Yellow - soft tissues and brain. Blue - skull bones.
