To illustrate the MR imaging features of anatomical variants of ligaments, muscles and tendons at the ankle. MATERIAL AND METHODS. The MRI features of the typical anatomy of the ankle is first reviewed in order to better understand the appearance of anatomical variants. The features of those anatomical variants are reported based on data from the literature and from a retrospective study of 63 ankle MRI and/or MR-arthrography performed for chronic instability.
Ankle anatomical variants can be separated into 3 groups For each variant, we report the frequency, the differential diagnosis and the potential clinical consequence that may, at times, require a specific treatment.
Anatomical variants are important to consider because these structures can simulate disease and can sometimes be symptomatic.
阐述踝关节韧带、肌肉和肌腱解剖变异的磁共振成像（MR）特征。材料与方法：首先回顾踝关节典型解剖结构的MRI特征，以便更好地理解解剖变异的表现。基于文献数据以及对63例因慢性不稳定而行踝关节MRI和/或MR关节造影的回顾性研究，报告这些解剖变异的特征。
踝关节解剖变异可分为3组。对于每种变异，我们报告其发生率、鉴别诊断以及有时可能需要特定治疗的潜在临床后果。
解剖变异很重要，需要考虑，因为这些结构可能模拟疾病，有时还会出现症状。
