Twenty-two cases of cerebellar infarction were diagnosed by clinical findings, computerized tomography (CT), magnetic resonance image (MRI) and autopsy. Most of the infarctions occurred in the territory of the posterior inferior cerebellar artery (18/22). The most common and earliest symptoms were dizziness or vertigo (19/22), which occurred repeatedly and were accompanied by nausea and vomiting. The symptoms and signs of cerebellar lesion such as unsteady gait, limb and/or trunk ataxia, dysarthria were also the main clinical manifestations. However, in a number of patients there were no cerebellar symptoms or signs (9/22). Rapid deterioration of consciousness suggested acute compression of the brainstem, where the prognosis would be poor. CT scan made it possible to diagnose cerebellar infarction in the patients. But CT is not a satisfactory instrument in identifying this disease. MRI without bony artifacts from the posterior fossa has much higher resolution and renders the infarction to be visualized earlier. It may be regarded as the most ideal instrument in diagnosing this disease.
通过临床表现、计算机断层扫描（CT）、磁共振成像（MRI）及尸检确诊了22例小脑梗死病例。大多数梗死发生在小脑后下动脉供血区域（18/22）。最常见且最早出现的症状是头晕或眩晕（19/22），症状反复出现并伴有恶心和呕吐。小脑病变的症状和体征，如步态不稳、肢体和/或躯干共济失调、构音障碍也是主要临床表现。然而，一些患者并无小脑症状或体征（9/22）。意识迅速恶化提示脑干急性受压，预后较差。CT扫描能够诊断患者的小脑梗死。但CT在识别这种疾病方面并非令人满意的检查手段。没有后颅窝骨质伪影的MRI具有更高的分辨率，能更早显示梗死灶。它可被视为诊断这种疾病的最理想检查手段。
