A rare case, 32-year-old man, of cerebellar infarction with the occurrence of the 8th cranial nerve symptoms was reported. On the neuro-otological examination, hearing test and caloric test showed a severe hearing loss and no response on the right side, respectively, and the spontaneous horizontal nystagmus fixed to the left direction was observed. Magnetic resonance (MR) imaging showed the infarctions in the areas of anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA) on the right side. On the 14th illness day, the 8th cranial nerve symptoms disappeared, and on the 12th illness day, right hearing level and caloric response were significantly improved. We suggested that such an early recovery of the subjective symptoms and neuro-otological findings may be attributable to the recanalized circulation disturbance or the development of collateral circulation.
报告了一例罕见病例，一名32岁男性，患有小脑梗死并出现第八颅神经症状。在神经耳科学检查中，听力测试和冷热试验分别显示右侧严重听力损失且无反应，并观察到向左方向固定的自发性水平性眼球震颤。磁共振成像显示右侧小脑前下动脉（AICA）和小脑后下动脉（PICA）区域梗死。在患病第14天，第八颅神经症状消失，在患病第12天，右侧听力水平和冷热反应显著改善。我们认为主观症状和神经耳科学检查结果的这种早期恢复可能归因于再通的循环障碍或侧支循环的形成。
