BACKGROUND
Pulsatile tinnitus occurs due to turbulent blood flow through a stenotic vessel including the internal carotid artery. The presence of sensorineural hearing loss suggests involvement of the posterior circulation vasculature.
CLINICAL PRESENTATION
A 58-year-old woman presented to the ear, nose and throat clinic with acute onset of right ear pulsations and high-pitched tinnitus. An audiogram demonstrated mild sensorineural hearing loss in the right ear. Her computed tomography angiogram revealed moderate stenosis of the right internal carotid artery and she underwent revascularization with angioplasty and stent placement. A repeat audiogram demonstrated improvement in sensorineural hearing loss in the right.
CONCLUSION
Pulsatile tinnitus and unilateral sensorineural hearing loss maybe a reversible manifestation of a stenotic internal carotid artery.
背景
搏动性耳鸣是由于狭窄血管（包括颈内动脉）中的血流湍流引起的。感音神经性听力损失的存在提示后循环血管受累。
临床特征
一名 58 岁女性因右耳搏动和高音调耳鸣急性发作到耳鼻喉科就诊。听力图显示右耳轻度感音神经性听力损失。她的 CT 血管造影显示右侧颈内动脉中度狭窄，行血管成形术和支架置入术进行血运重建。重复听力图显示右侧感音神经性听力损失有所改善。
结论
搏动性耳鸣和单侧感音神经性听力损失可能是颈内动脉狭窄的一种可逆表现。
