Definition

Meningioma is a tumor that arises from the meninges — the membranes that surround your brain and spinal cord. The majority of meningioma cases are noncancerous (benign), though rarely a meningioma can be cancerous (malignant).

Meningioma occurs most commonly in women. Most people develop meningioma as adults, after age 40. But meningioma can occur at any age, including childhood.

Even if a meningioma is benign, it isn't harmless. A meningioma can press on the brain and spinal cord, causing complications such as vision loss or paralysis. The signs and symptoms you experience depend on the size and location of the meningioma and what parts of the nervous system are affected. Meningioma treatment options include surgery and radiation, though sometimes immediate treatment isn't necessary.
