Meningiomas are benign, slow-growing tumors, classified as brain tumors, but actually growing in the three protective membranes that surround the brain (meninges). Sometimes they cause thickening or thinning of adjoining skull bones. Meningiomas do not spread to other areas of the body. Signs and symptoms vary according to the size and location of the tumor. The exact cause of this condition is unknown.
