To corroborate the vascular etiology of sudden sensorineural hearing loss (SNHL) utilizing magnetic resonance imaging (MRI).
A 24-year-old male with a history of sickle cell disease experienced sudden SNHL and right horizontal nystagmus, without accompanying vertigo.
Audiometric evaluation revealed left-sided SNHL, predominantly affecting high frequencies. Video head impulse testing demonstrated isolated dysfunction of the left posterior semicircular canal. An urgent brain MRI identified a recent punctiform ischemic stroke in the frontal region. A subsequent MRI, conducted with a 4-hour delay and post-contrast enhancement, highlighted a hyperintense signal within the left cochlear region and the left posterior semicircular canal.
The investigative results substantiate an infarction in the territory of the cochlear artery, precipitated by a vaso-occlusive event, thereby reinforcing the vascular hypothesis of cochleovestibular artery syndrome. This case underscores the congruence between clinical observations and delayed post-contrast MRI findings.
利用磁共振成像（MRI）证实突发性聋（SNHL）的血管病因。
一名 24 岁男性，有镰状细胞病史，出现突发性 SNHL 和右侧水平性眼球震颤，但无伴随眩晕。
听力评估显示左侧 SNHL，主要影响高频。视频头脉冲测试显示左侧后半规管孤立性功能障碍。紧急脑部 MRI 发现额区近期点状缺血性中风。随后进行的 MRI，在 4 小时延迟和增强后，显示左侧耳蜗区和左侧后半规管内呈高信号。
研究结果证实，由于血管阻塞事件导致耳蜗动脉供血区梗死，从而支持耳蜗前庭动脉综合征的血管假说。该病例突出了临床观察结果与延迟后增强 MRI 发现之间的一致性。
