目的探讨小脑梗死的临床表现及影像学特点,以减少误诊。方法对37例小脑梗死患者的临床资料进行回顾性分析。37例中男27例,女10例,平均年龄67.1岁。结果临床表现复杂多样,主要表现为:眩晕、呕吐、步态不稳。37例中临床误诊9例,后经MR I检查确诊。单纯小脑梗死共18例(右侧小脑8例,左侧小脑6例,双侧小脑4例),除小脑梗死外同时伴颅内其他部位梗死灶者共19例。小脑梗死以小脑上动脉供血区最常见,共24例,占64.9%。CT尤其是MR I对早期诊断具有重要意义。结论小脑梗死容易误诊,头颅MR I确诊小脑梗死优于头颅CT。
Objective To investigate the clinical manifestations and imaging features of cerebellar infarction to reduce misdiagnosis. Methods The clinical data of 37 patients with cerebellar infarction were retrospectively analyzed. There were 27 males and 10 females in 37 cases, with an average age of 67.1 years. Results The clinical manifestations of complex and diverse, mainly as follows: dizziness, vomiting, unsteady gait. Of the 37 cases, 9 were misdiagnosed and confirmed by MRI examination. Simple cerebellar infarction in 18 cases (right cerebellum in 8 cases, 6 cases of left cerebellum, 4 cases of bilateral cerebellum), in addition to cerebellar infarction with other parts of the brain at the same time with a total of 19 cases of infarction. Cerebellar infarction to the most common cerebellar artery blood supply area, a total of 24 cases, accounting for 64.9%. CT especially MRI is of great importance for early diagnosis. Conclusions It is easy to misdiagnose cerebellar infarction and cranial MRI diagnosis of cerebellar infarction is better than cranial CT.
