title: Intracranial aneurysms and optic glioma--an unusual combination: a case report.
abstract: BACKGROUND
  The coexistence of glial high grade tumors (glioblastoma, anaplastic astrocytoma) and cerebral aneurysms is common but the association with optic glioma is rare. The treatment of these associated lesions is problematic.
  
  
  METHODS
  A 36-year-old white woman presented to our institution with recurrent attacks of headache. Her preoperative radiological studies revealed a lesion of her left optic nerve with extension to the optic chiasma, an aneurysmatic dilatation of the left carotid bifurcation, a second aneurysm on the left of her middle cerebral artery, and a third one on her right anterior cerebral artery in the A2 tract. A left pterional approach was used to remove the tumor and clip the three aneurysmatic dilatations in a single stage.
  
  
  CONCLUSIONS
  We report this unusual case of optic glioma associated to multiples aneurysms and review the pertinent literature. An adequate knowledge of this association is mandatory to plan the correct approach to avoid complications.
