Abstract
Ankle effusions may be detected on lateral radiographs by observing a teardrop-shaped density extending anteriorly from the ankle joint along the neck of the talus. The normal and abnormal radiographic appearances of the ankle are discussed and the teardrop sign is identified.
摘要
通过观察沿着距骨颈从踝关节向前延伸的泪滴状密度影，可在踝关节侧位X线片上检测到踝关节积液。文中讨论了踝关节正常和异常的影像学表现，并确定了泪滴征。
