We present a case of a sagittal sinus dural arteriovenous fistula manifesting as dysphonia secondary to vocal fold paresis. The patient presented with a 6-week history of hoarseness. Imaging studies demonstrated findings suggestive of a dural arteriovenous fistula affecting the superior sagittal sinus. Direct laryngoscopy demonstrated paresis of the right vocal fold. We hypothesized that pressure on the vagus nerve from a dilated and arterialized internal jugular vein within the jugular foramen was responsible for the cranial neuropathy. The patient’s dysphonia resolved with embolization of the fistula, and repeat laryngoscopy showed resolution of the vocal fold paresis.

矢状窦硬脑膜动静脉瘘表现为单侧声带麻痹

我们提出了一例矢状窦硬脑膜动静脉瘘，表现为继发于声带麻痹的发音困难。患者出现声音嘶哑 6 周。影像学研究表明，硬脑膜动静脉瘘影响上矢状窦。直接喉镜检查显示右侧声带麻痹。我们假设颈静脉孔内扩张和动脉化的颈内静脉对迷走神经的压力是造成颅神经病变的原因。栓塞瘘管后，患者的发音障碍得到缓解，重复喉镜检查显示声带麻痹消失。
