Meningioma is the most common type of primary brain tumor and arises from the meninges, the membranes that surround the brain and spinal cord.

There are several different types of meningioma, including: convexity meningiomas, which grow on the surface of the brain; intraventricular meningiomas, which grow within the ventricles of the brain; olfactory groove meningiomas, which grow near the olfactory nerve, located between the brain and nose at the base of the skull; and sphenoid wing meningiomas, which grow along a ridge of bone behind the eyes.

Meningioma is typically a slow-growing cancer, which means it often doesn’t present symptoms; however, patients should seek medical attention if they experience a sudden onset of seizures or a sudden change in vision as these may be signs of meningioma.

The GW Cancer Centers’s Neuro Oncology Program strives to provide patients with the best possible care through its team of world-class doctors who specialize in diagnosing and treating meningioma and other types of brain tumors.
