A meningioma is a central nervous system tumor, or brain tumor, originating from the meninges, the covering of the brain and spinal cord called dura. Meningiomas make up 41% of newly diagnosed brain tumors, and of those, the majority are benign.

Brain tumors are fairly uncommon and occur in about 1 in 10,000 people, but it is important to recognize when common symptoms, like headaches, should be investigated.
