Trigeminal neuralgia (TGN) is often caused by a neurovascular conflict at the root entry zone of the fifth nerve. Dural arteriovenous fistula (DAVF) accounts for 3%-4% cases of TGN. We report a posttraumatic head injury patient, presenting with gait ataxia and right facial pain. Radiographic evidence with magnetic resonance imaging and digital subtraction angiography was suggestive of DAVF. Surgical clipping and obliteration of fistula alleviated the TGN.

三叉神经痛（TGN）通常由第五神经根部入口区的神经血管冲突引起。硬脑膜动静脉瘘（DAVF）占TGN病例的3%-4%。我们报告一例创伤后头部损伤患者，表现为步态共济失调和右侧面部疼痛。磁共振成像和数字减影血管造影的影像学证据提示为DAVF。手术夹闭和瘘管闭塞缓解了TGN。
