We report a case of bilateral hearing loss caused by decreased vascular flow in the anterior inferior cerebellar artery (AICA) territory. A 74-year-old man who experienced right hearing loss 5 months ago presented with bilateral deafness and right cerebellar ataxia; however, no ischemic lesion was detected in the bilateral AICA area. After stroke treatment, hearing loss was improved. One month later, we obtained blood flow improvement in the left AICA territory on single-photon-emission computed tomography and vertebral artery stenosis on magnetic resonance angiography. Therefore, clinicians should recognize that bilateral hearing loss may be related to stroke in the vertebrobasilar artery area.
我们报告一例由小脑前下动脉（AICA）区域血流减少引起的双侧听力丧失病例。一名74岁男性在5个月前出现右耳听力丧失，随后出现双侧耳聋和右小脑共济失调；然而，双侧AICA区域未检测到缺血性病变。经过中风治疗后，听力丧失有所改善。1个月后，我们通过单光子发射计算机断层扫描发现左侧AICA区域血流改善，磁共振血管造影显示椎动脉狭窄。因此，临床医生应认识到双侧听力丧失可能与椎基底动脉区域的中风有关。
