What Is a Cerebral Meningioma?
A cerebral meningioma is a brain tumor, although it is not a tumor of brain tissue. It is instead a tumor of the meninges, the thin layers of tissue that cover the brain and spinal cord. In most cases, a meningioma is a benign brain tumor, meaning it is not cancerous. What causes cerebral meningiomas is not known. They are more common in adult women, but they can also occur in men and in of people of all ages. Some scientists believe that a combination of environmental and genetic factors can lead to them.
