case_images: (A) Facial aspect of patient 1 at the age of 6 years showing prominent forehead and hypertelorism. (B) Face of patient 2 at the age of 18 months. Prominent forehead, synophris, hypertelorism and mildly downward slanting palpebral fissures.

case_images: (A) Routine electrophalography (EEG) reveals focal sharp-waves (left, frontoparietal), rhythmic 6 Hz electrical activity and signs of focal cerebral dsfunction with a frontal theta-waves slow activity in the frontal area. (B) The EEG examination of patient 2. Frontotemporal sharp-wave complexes on the left side and rhythmical 4-5 Hz activity.

case_images: The EEG examination was pathological due to frontotemporal sharp-wave complexes on the left hemisphere and a rhythmic 4-5 Hz activity (Figure 2B).
