Intraventricular noncolloid epithelial cyst in an infant.

A rare case of giant intraventricular noncolloid epithelial cyst associated with multicompartmental hydrocephalus in an infant is presented. The cyst was located in the third ventricle and extended through the foramina of Monro into the lateral ventricles. Multiple modes of therapy were performed, including shunting procedures and transcortical and transcallosal cystostomies. It is concluded that extensive cystostomy coupled with a shunting procedure is the preferred method of treatment for giant cystic lesions around the foramina of Monro, if total excision is not feasible.
