目的探讨小脑梗死与临床表现的关系。方法对 42例小脑梗死患者的临床及 CT、MRI资料进行分析 ,并对 CT及 MRI表现按脑动脉支配区进行分型。结果小脑前下动脉区 2 4例 ,小脑后下动脉区 10例 ,小脑上动脉区 8例。结论小脑梗死临床特点多变 ,缺乏特异性 ,而 MRI可提高对本病的诊断水平。 Objective To investigate the relationship between cerebellar infarction and clinical manifestations. Methods The clinical and CT, MRI data of 42 patients with cerebellar infarction were analyzed. The CT and MRI findings were classified according to the cerebral arterial dominant area. Results There were 24 cases of anterior inferior cerebellar artery, 10 posterior inferior cerebellar artery and 8 superior cerebellar artery.
