Meningioma
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.
