Clinical approach to the child with a large head
1Section of Pediatric Neurology, Department of Neurology, Indiana University School of Medicine, Indianapolis, Indiana, USA.
Abstract:
Majority of children has head size that is appropriate for age and gender. But a few have either too small or too large head at birth or may be of postnatal acceleration. Abnormality of head circumferences is determined by brain size, including any malformations and space occupying lesions, cerebrospinal fluid (CSF) and blood volume, presence of subdural fluid and thickness of skull bones and overlying tissue scalp. Macrocephaly is used when the head size exceeds the mean by more than two standard devotions of age and gender. Macrocephaly is seen in association with several cranioskeletal dysplastic conditions.
