title: Intraventricular arachnoid cyst. Report of two cases.
abstract: Two patients with intraventricular arachnoid cysts are reported and a brief review of the relevant literature is presented. Arachnoid cysts are usually extracerebral or extraventricular. Intraventricular arachnoid cysts are rare: including the two cases reported here, only five cases have been described. The following characteristics were noted in these five patients: all were young; headache was the initial symptom in four; the cyst was in the trigone of a lateral ventricle in four; and there was dilatation of the inferior horn in three.
