Intraorbital arteriovenous fistula is a rare vascular disease characterized by an acquired arteriovenous communication without direct cavernous sinus involvement. Intraorbital arteriovenous fistula may develop slowly and present similarly to other insidious orbitopathies, such as carotid-cavernous fistula. The authors present a case of a superficial temporal artery to superior ophthalmic vein fistula arising in the absence of trauma or prior surgery. This is the first report of a spontaneous intraorbital arteriovenous fistula arising between these vessels and further describes the rare occurrence of intraorbital arteriovenous fistula.
The authors report a case of spontaneous superficial temporal artery to superior ophthalmic vein fistula with slowly progressive proptosis treated with embolization.
