title: [Optic nerve pilocytic astrocytoma with retinal involvement].
abstract: BACKGROUND
  This is an atypical case of a pilocytic astrocytoma that involved the optic nerve (ON) and the retina.
  
  
  METHODS
  The patient was a 30-year-old male, who had attended ONCE since his early childhood because of the suspicion of an intraocular tumor. The ophthalmology exploration showed an ON and retinal coloboma in the right eye and microphthalmy, shutting of the pupil, retinal detachment and proof of an intraocular tumor in the left eye. The MR revealed an ON tumor that involved the retina. The histopathological study after enucleation was pilocytic astrocytoma.
  
  
  CONCLUSIONS
  Long standing congenital pathology in a blind patient does not exclude the possibility of the patient suffering from other pathology as well.
