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.
颅内海绵窦硬脑膜动静脉瘘（CS-dAVF）很少引起颅内出血。我们报告1例以颅内出血为表现的CS-dAVF。一名62岁男性出现伴有意识障碍的强直性阵挛性惊厥，被转诊至我院。CT扫描显示蛛网膜下腔出血和右侧额叶皮质下出血。血管造影显示右侧CS-dAVF，仅引流至右侧外侧裂静脉。采用可脱性弹簧圈行经静脉栓塞术。栓塞术后，CS-dAVF完全消失，患者无症状出院。我们总结了包括我们的病例在内的14例报告的伴有颅内出血的CS-dAVF病例。所有病例均通过脑静脉进行逆向引流。
