title: [Metastases of meningioma. Apropos of 2 cases].
abstract: Two cases of meningiomas with metastasis are presented. The first case is typically a fibroblastic meningioma. After a local recurrence, dissemination occurs in the CSF with multiples localizations. The second case is a parasagittal meningioma of meningotheliomatous type. After two recurrences, a lymph node metastasis is discovered. Three modes of dissemination are known: through the blood vessels, the lymphatics or the CSF. The different spreads and mechanisms are discussed.
