The Wyburn-Mason syndrome. Concomitant chiasmal and fundus vascular malformations.

We report a 56-year-old female with a 50-year history of a progressive chiasmal syndrome who was found to have a suprasellar arteriovenous malformation involving the chiasm and both optic nerves associated with an unusual fundus picture consistent with the Wyburn-Mason syndrome. A review of the literature of this rare syndrome is also presented.
