Who is at risk for developing meningiomas?
Meningiomas can affect anyone. Women account for two-thirds of all meningiomas. However, malignant meningiomas are found more often in men. Also, they are most often found in adults between 30 and 70 years of age. These tumors are more commonly found in Africa than Europe or North America. In the United States, there are about two cases of symptomatic meningiomas per 100,000 persons annually.
