Intracranial optic nerve angioblastoma.

Angiomatous tumours causing visual disturbances are well known (Reese, 1963). The tumour may be isolated (mainly in the orbit and choroid), or it may be a manifestation of von Hippel's disease (in the retina and on the optic disc), Sturge-Weber's disease (in the choroid and intracranial), or Coats's disease (in the retina). Angiomatous tumours of the optic nerve are extremely rare. This communication presents an intracranial optic nerve angioblastoma found by chance at necropsy 23 years after the onset of visual disturbances which led to unilateral optic atrophy.
