Intraventricular meningioma in childhood. Case report

Abstract

Central nervous system tumors are the first location of solid tumors in childhood, with predominance of the embryonic lineage and relative absence of gliomas. Meningiomas are usually benign tumors of the central nervous system, arising from the arachnoid cell layer. They are a rarity in childhood, but
when they do appear in this age group, the intraventricular location is more frequent than in adults
and the usual location is in the trigone of the lateral ventricles and more rarely in the III and IV
ventricles. These are slow-growing tumors; moreover, as all intraventricular tumors, they present an
asymptomatic growth period, because tumor grows displacing the cerebrospinal fluid (CSF) from the
ventricular cavity, so it does not affect the brain tissue. For this reason, they may attain a large volume
before becoming symptomatic.
