A meningioma is a type of tumor that develops from the meninges, the membrane that surrounds the brain and spinal cord. There are three layers of meninges, called the dura mater, arachnoid and pia mater.eningiomas are most common in people between the ages of 40 and 70. They are more common in women than in men. Among middle-aged patients, there is a marked female bias, with a female: male ratio of almost 3 to 1 in the brain and up to 6 to 1 in the spinal cord.
