text: A meningioma is a tumor that occurs in the meninges, the tissue layer that covers the brain and spine.
  Meningiomas grow on the surface of the brain or spinal cord. They are usually benign because they rarely spread and they grow very slowly.
  Symptoms
  Meningioma patients most commonly experience painful headaches, weakness or paralysis, a reduction in their field of vision and difficulties with speech.
  The specific symptoms will depend on the tumor's location.
  Diagnosis
  If the meningioma is small and slow-growing, and the symptoms are minimal or easily controlled, diagnosis will involve observation and annual magnetic resonance imaging (MRI) scans.
  Treatment
  Surgery may be necessary to determine whether the meningioma is a faster growing, malignant type known as anaplastic meningioma.
