A left-handed 18-year-old boy was examined after three episodes of loss of consciousness within the six-month period prior to admission. His history included fetal distress accompanied by prolonged and complicated delivery by high forceps extraction. There were no left-handed individuals among the other family members. The three episodes of loss of consciousness evolved from sudden onsets of right-sided numbness starting at the hand, moving to the shoulder and then to the side of the mouth. In each episode, after a few minutes he regained consciousness but was confused and sleepy for the rest of the day. Onadmission, he appeared somewhat clumsy, but his limbs did not look short or deformed. He had mild right hemiparesis. Axial- and coronal-projection computed tomograms of the head were obtained (Figs 1 and 2). Skull roentgenograms from another hospital were reviewed (Fig 3).
