This entity may occur in persons 15 years of age or younger. Our experience with the following recent case has prompted a review of the literature.Report of a CaseĀ  A 15-year-old high-school football player was admitted in a semiconscious condition with marked hemiparesis on the left. He had been in excellent health except for a mild headache prior to "warm-ing up" on the football field. He suddenly fell to the ground unconscious and had a convulsion. He was taken to the office of a nearby physician and sent to the Mary Hitchcock Memorial Hospital. On examination he was drowsy, confused, and incontinent but not aphasic. There were no bruises about his scalp. His pulse was 60 beats per minute, but other vital signs were normal.
