Abstract
Computerized axial tomography [CT] is a safe, non-invasive technique for measurement of ventricular size. A review of 44 children without myelodysplasia who were evaluated for inappropriately enlarging heads, documented a group of 20 children presenting at 5 mo.-2 yr of age with megalencephaly or mild communicating hydrocephalus. Of these, only 2 required shunts. During recent examinations, most children demonstrated a normal development. Serial neurological examination, developmental evaluation and head-circumference measurements, in association with CT, have proved effective in the assessment and management of this particular group of children with large heads.
