Abstract
We report the case of a 68-year-old woman with a chronic unilateral red eye for 3 months. The ophthalmologic exam showed engorged episcleral vessels, proptosis and chemosis. Motility, visual acuity and fundus examination were normal. Neurological examination was also unremarkable. Given the subacute nature of the proptosis in association with engorged episcleral vessels, brain MRI and MRA were performed, demonstrating a right dural-cavernous sinus fistula. After two attempts via the femoral and facial veins, the dural fistula was accessed and treated via the right superior ophthalmic vein. The fistula was occluded and the symptoms regressed in 48 hours. Arteriography at 3 months confirmed a complete cure.
