Ataxia is defined as a lack of coordination of voluntary movement, caused by a variety of factors. Ataxia can be classified by the age at onset and type (chronic or acute). The causative lesions involve the cerebellum and cerebellar connections. The correct, appropriate use of neuroimaging, particularly magnetic resonance imaging, can make the diagnosis relatively straightforward and facilitate implementation of the appropriate clinical management. The purpose of this pictorial essay is to describe the imaging findings of ataxia, based on cases obtained from the archives of a tertiary care hospital, with a review of the most important findings. We also discuss and review the imaging aspects of neoplastic diseases, malformations, degenerative diseases, and hereditary diseases related to ataxia.
共济失调被定义为由多种因素引起的随意运动协调障碍。共济失调可根据发病年龄和类型（慢性或急性）进行分类。致病病变累及小脑及小脑连接。正确、恰当地使用神经影像学检查，尤其是磁共振成像，可使诊断相对简单直接，并有助于实施适当的临床管理。本图文综述的目的是基于一家三级医疗中心存档病例描述共济失调的影像学表现，并回顾最重要的发现。我们还将讨论和回顾与共济失调相关的肿瘤性疾病、畸形、退行性疾病和遗传性疾病的影像学特征。
