Of 234 children with seizures, 12.8% had abnormal skull roentgenograms. Microcephaly was the most common abnormality (10%); there were two cases of positional molding, and single cases of unilateral cerebral atrophy, sagittal synostosis, split sutures, arrested hydrocephalus, and falx calcification comprised the remainder.
Microcephaly was unsuspected in seven patients. Radiologic findings positively affected management in only one other patient. The value of negative information is difficult to assess, but this study suggests that convulsions alone do not constitute a valid indication for skull roentgenograms.
