摘　　要：分析经ＭＲＩ检查诊断的无小脑体征的小脑梗塞６３ 例。发现无小脑定位体征性小脑梗塞发病率高，其临床表现主要为椎基底动脉系统短暂性脑缺血发作（ＴＩＡ）、脑干梗塞及颈内动脉系统病变。病变部位以ＰＩＣＡ与ＳＣＡ区的分水岭梗塞最为常见，其次为ＰＩＣＡ区及ＳＣＡ区供血区梗塞，ＡＩＣＡ区最少，梗塞灶的大小以腔隙性梗塞为主，其中２４ 例合并脑干梗塞。Abstract 63 cases of cerebellar infarction without signs of localization diagnosed by MR imaging were analyzed. A high incidence was found. Its clinical characteristics were those of vertebrobasilar transient ischemic attacks (TLA), brainstem infarction, and vascular disease of internal carotid artery. The location of the infarction, were most commonly seen in the watershed of the posterior inferior cerebellar artery (PICA) and the superior cerebellae artery (SCA). The second was in the area of PICA and SCA, and less common in the region of the anterior inferior cerebellar artery (AICA). The sizes of most lesions were mainly lacumar infarction. Twenty four cases were accompanied with brainstem infarction.
