This is a tumor of the meninges, the membranes that line the surface of the brain. It is generally benign (non-cancerous), but its growth can put pressure on surrounding brain tissues. This can lead to symptoms ranging from headaches to seizures and sensory disturbances. The tumor can be removed surgically in some cases, leading to a complete cure. Here, two sections (different levels) of the same brain show a meningioma copmressing the frontal lobe and distorting the underlying brain.
