背景小脑前下动脉（AICA）的耳道环引起的耳道内动脉瘤是非常罕见的。病例介绍我们报告了一个60岁的男子提出了严重的眩晕和突发性左侧听力损失与蛛网膜下腔出血引起的囊状动脉瘤破裂引起的耳道环的AICA，这是完全埋在耳道。术中，我们确定了闭塞的内听动脉所产生的耳道环的AICA，动脉瘤的起源，并进行neck clipping.ConclusionThese研究结果表明，内听动脉闭塞是一个潜在的原因，听觉和前庭功能的损失。
BackgroundIntrameatal aneurysms arising from the meatal loop of the anterior inferior cerebellar artery (AICA) are extremely rare.Case presentationWe report a 60-year-old man presenting with severe vertigo and sudden left hearing loss associated with subarachnoid hemorrhage caused by rupture of a saccular aneurysm arising from the meatal loop of the AICA, which was entirely buried in the meatus. Intraoperatively, we identified the occluded internal auditory artery arising from the meatal loop of the AICA, where the aneurysm originated, and performed neck clipping.ConclusionThese findings suggest that internal auditory artery occlusion is a potential cause of loss of auditory and vestibular functions.
