    Abstract:
    A case of cavernous sinus dural arteriovenous fistula (CS-DAVF) presenting intracerebral venous hemorrhage was reported. An 81-year-old woman was suffered from generalized convulsion accompanied by right conjunctival hyperemia and edema. Computed tomography scan revealed intracerebral hematoma involving right putamen and perifocal edema extraordinarily expanded to inferior part of the right frontal lobe and insular cortex. Cerebral angiography showed a CS-DAVF with retrograde leptomeningeal venous drainage (RLVD) not only to superficial middle cerebral vein but to basal vein of Rosenthal (BVR). Transvenous embolization was performed using mechanically detachable coils and free fibered platinum coils. After embolization, RLVD disappeared and conjunctival symptoms were improved. Hemorrhagic risk of this patient was discussed, based on her angiographical findings. We speculated that deep venous drainage to BVR through uncal vein, in case with poor venous collateral geometry, is one of the risk factor of cerebral hemorrhage.
