Meningioma

A tumor that arises from the membranes surrounding the brain and spinal cord.

Overview

It isn't clear what causes a meningioma. Radiation therapy, female hormones, and genetics may play a role. In most cases, the condition is noncancerous.

Symptoms

Symptoms may include changes in vision, headaches, hearing loss, and seizures.

Treatments

A small, slow-growing meningioma that isn't causing signs or symptoms may not require treatment. When needed, treatment might involve surgery or radiation.
