Carotid artery dissection is an uncommon entity associated with head and neck pain, partial Horner's syndrome, amaurosis fugax, and brain ischemia, which may all occur in isolation or in combination. Herein, we report a rare case of cervical artery dissection in which pulsatile tinnitus was the only reported symptom. A 38-years-old man attended our hospital with a 4-days history of left side pulsatile tinnitus which began after stumbling. He had no other symptom. MRA showed luminal stenosis with pseudo lumen of the internal carotid artery. The patient was diagnosed with left internal carotid artery dissection and treated with antihypertensive therapy accordingly. After 2 months, the stenosis and tinnitus spontaneously resolved.
颈动脉夹层是一种不常见的病症，与头颈部疼痛、部分霍纳综合征、一过性黑矇和脑缺血相关，这些症状可能单独出现或合并出现。在此，我们报告一例罕见的颈动脉夹层病例，其中搏动性耳鸣是唯一报告的症状。一名38岁男性因左侧搏动性耳鸣4天前来我院就诊，耳鸣始于绊倒后。他没有其他症状。磁共振血管造影显示颈内动脉管腔狭窄并伴有假腔。患者被诊断为左颈内动脉夹层，并相应地接受了降压治疗。2个月后，狭窄和耳鸣自行缓解。
