A meningioma is a tumor that occurs in the meninges, the tissue layer covering the brain and spine. Unlike other types of neurological tumors, meningiomas grow on the surface of the brain or spinal cord. Most are considered benign because they grow slowly and seldom spread.


Meningioma patients most commonly experience painful headaches, weakness or paralysis, a reduction in their field of vision and difficulties with speech. Specific symptoms depend on the tumor's location.

Observation combined with annual magnetic resonance imaging (MRI) scans may be recommended if the tumor is small and slow growing, and if the related symptoms are minimal or can be controlled with medications.


Surgery may be indicated, however, to determine whether the meningioma is a faster growing, malignant type known as anaplastic meningioma. In those cases, your physician may recommend these alternatives:

  • Minimally invasive surgery followed by conventional radiation therapy or stereotactic radiosurgery
  • Targeted therapy with octreotide

Clinical trials also are an option.
