[Intracranial arachnoid cysts in children. Review of 34 cases].
Clinical, radiological, and therapeutical aspects of 34 cases of childhood intracranial arachnoid cysts are reviewed. Two thirds (23) were located supratentorially, the remaining 11 had an infratentorial localization. Of the first group 15 were situated at the sylvian region, 6 were hemispherical and 2 suprasellar. Clinical manifestations were present before 6 months of age in 68% of all the cases. Macrocephaly and focal seizures were the most common clinical findings. Skull X-Ray examination was helpful only when cysts were located at sylvian region. CT Brain Scan was positive in all cases (32) in which it was performed, dynamic studies with Metrizamide were necessary in 6 cases and arteriography in 4 cases to definitively prove the diagnosis. Surgical approach (removal of cysts or cyst/ventriculo-peritoneal shunting) was undertaken in 20 cases, with unequal results. Authors comment on possible etiopathogenic factors, indications for use of dynamic studies with Metrizamide and rational guide for surgical therapy on these patients.
