Extracerebral anaplastic meningioma.

Key Clinical Message: Conventional treatments of anaplastic meningioma include surgery and radiotherapy. Temozolomide is also an option. Metastases to extracerebral organs are very rare and hardly manageable. Antiangiogenic drugs could represent a salvage therapy.

Abstract: Anaplastic meningioma is an unusual tumor subtype that rarely involves organs outside the brain. In our case, a patient with cerebral meningioma developed lung metastases after 19 years from the initial tumor appearance. This unpredictable behavior could make complex the diagnosis.
