A 6½-year-old girl was examined for short attention span, nightmares, and tantrums. Her neonatal history was that she had been the product of a full-term gestation and a normal delivery. Her neonatal course and psychomotor development had been uneventful. At 10 months of age, she was in an automobile accident and suffered head trauma without a loss of consciousness. She had a transient right hemiparesis that cleared in ten days. Roentgenography of the skull was obtained (Fig 1).
At 6½ years of age, physical examination showed there was a small defect in the left calvaria on palpation and mild, right-sided lateral rectus weakness. A second skull roentgenogram was obtained (Fig 2).
