title: [Fractionated stereotactic radiotherapy in optic nerve sheath meningioma].
abstract: METHODS
  A 56-year-old woman with a right optic nerve sheath meningioma and visual loss, was treated with fractionated stereotactic radiotherapy. This resulted in an almost complete recovery of her visual acuity.
  
  
  CONCLUSIONS
  Currently there are many different alternatives available for the management of an optic nerve sheath meningioma: observation, surgery, conventional radiotherapy and fractionated stereotactic radiotherapy. The last of these treatments has been demonstrated to preserve or improve vision in 2 out of 3 treated patients, with fewer side effects, and has not been associated with recurrent disease or tumor progression.
