摘　　要：目的探讨小脑前下动脉(AICA)梗死的临床及影像学特点。方法回顾性分析32例患者的临床资料。结果AICA梗死绝大多数以眩晕、小脑性共济失调为首发表现。第Ⅷ对颅神经受累是其特征性表现。MRI上表现为桥脑外下侧或(和)小脑中脚区域的梗死。AICA梗死预后较好,但有可能进展为基底动脉梗死。结论AICA梗死的诊断主要依靠MRI,预后较好。Objective To investigate the clinical and imaging features of anterior inferior cerebellar artery （AICA） territory infarction. Methods We retrospectively analyzed the clinical data of 32 patients. Results The main clinical features of AICA infarction were vertigo and cerebellar ataxia, with cranial nerve Ⅷ involvement as the characteristic presentation. MRI showed infarctions in lateral inferior pontine region or/and the area of middle cerebellar peduncle. The prognosis of AICA infarction was comparatively good, but the infarction might develop into basilar artery （BA） infarction. Conclusion The diagnosis of AICA infarction is primarily depended on MRI. The prognosis of AICA infarction was comparatively good.
