Benign meningioma metastasizing through CSF pathways: a case report and review of literature.

Metastasis of intraventricular meningiomas through CSF pathways is a rarity and only 4 cases have been reported in world literature describing meningiomas which were intraventricular and malignant. Here we report a case of benign intraventricular meningioma which had spread through CSF pathways, the recurrences as well as the primary tumor being benign in nature.
