The purpose is to review the findings of the intraarticular ankle impingement lesions using an imaging-based approach. Illustrations will be used to explain the anatomic basis, pathophysiology and main features of each impingement lesion. The role of diagnostic imaging in the management of these entities and the differential diagnoses will be discussed. 1. Imaging findings may relate to a range of soft tissue or bony pathologies that can predispose to painful limitation of joint motion or impingement. Diagnosis of ankle impingement remains clinical, however is aided by radiological findings. 2. Knowledge of the pathophysiology and the anatomy of the regions involved in each syndrome is important to understand the imaging findings. 3. Post-traumatic synovitis, intraarticular fibrous scar tissue, capsular scarring and bone abnormalities are frequently associated with this pathology. 4.Knowledge of the imaging findings and the differential diagnoses for the various ankle impingement syndromes is essential to avoid misdiagnosis that may delay the patient’s treatment.

Definition and general features Anatomy, demographics, pathophysiology, clinical findings, imaging findings, differential diagnoses and management of each ankle impingement syndrome (anterior, posterior, anterolateral, anteromedial and posteromedial)
