Diagnosis and management of an intraorbital vascular fistula.

A spontaneous intraorbital arteriovenous fistula is an extremely rare phenomenon. More commonly, arteriovenous fistulas occur spontaneously as carotid cavernous fistulas and dural cavernous fistulas or are secondary to trauma. Surgical approaches vary widely and each carries their own set of potential problems. The purpose of this single case report was to provide an example of a successful treatment of a rare, spontaneous intraorbital vascular fistula.
