[A case of cavernous sinus dural arteriovenous fistula presenting with intracranial hemorrhage]

Abstract

Intracranial cavernous sinus dural arteriovenous fistula (CS-dAVF) rarely causes intracranial hemorrhage. We report a case of CS-dAVF presenting with intracranial hemorrhage. A 62-year-old man presented tonic clonic convulsion with consciousness disturbance and was transferred to our hospital. CT scan revealed subarachnoid hemorrhage and right frontal subcortical hemorrhage. Angiography revealed right CS-dAVF which drained only into the vein of the right sylvian fissure. Transvenous embolization was performed using detachable coils. After embolization, CS-dAVF had completely disappeared and the patient was discharged without any symptom. We summarized the fourteen reported cases, including ours, of CS-dAVF with intracranial hemorrhage. All of them had retrograde drainage through cerebral veins.
