Our purpose was to show how difficult it is to diagnose a dural fistula of the cavernous sinus, which is an anomalous arteriovenous shunt within the dura mater extending from meningeal arteries to the cavernous sinus.A dural fistula was suspected in four female patients aged between 61 and 80, presenting with a red eye, dilated episcleral veins, exophthalmos and elevated intraocular pressure. A cerebral hyperselective angiography was performed in all cases.The cerebral angiography confirmed the diagnosis of a dural fistula in all cases, showing the early filling of the cavernous sinus followed by the draining vessel (posterior in case n. 4, anterior in cases n degrees 1, 2, 3). Case n degrees 2 was unilateral and cases n. 1, 3, 3 were bilateral. The blood flow was low in all cases. A successful embolization was performed in all patients with resolution of all symptoms.The diagnosis of dural fistulas is often difficult because of misleading clinical signs. It is documented by a cerebral angiography showing the feeding vessels and helping to choose either venous or arterial embolization which is the most suitable treatment.
