Risk factors for a meningioma include:

  • Radiation treatment. Radiation therapy that involves radiation to the head may increase the risk of a meningioma.
  • Female hormones. Meningiomas are more common in women, leading doctors to believe that female hormones may play a role.
  • An inherited nervous system disorder. The rare disorder neurofibromatosis type 2 increases the risk of meningioma and other brain tumors.
