肌骨超声在焦磷酸钙沉积病的应用价值

焦磷酸钙沉积病为焦磷酸钙晶体沉积于关节透明软骨和纤维软骨，以及关节周围组织，如滑膜、肌腱、滑囊，特征是软骨钙化，急性发作时称假性痛风。焦磷酸钙沉积病的临床表现多样，发病率随着年龄的增加而升高，对其进行准确诊断具有重要意义。目前最为广泛使用的是Ryan-McCarty诊断标准，包括滑液分析中存在焦磷酸钙晶体和典型的影像学下软骨钙化。肌骨超声的应用使其诊断的敏感性及特异性均有增高，本文就焦磷酸钙沉积病的超声应用价值进行综述。

Application value of musculoskeletal ultrasound in calcium pyrophosphate deposition disease

Calcium pyrophosphate deposition disease is the deposition of calcium pyrophosphate crystals on the hyaline cartilage and fibrous cartilage of the joint, and the tissues around the joint, such as the synovium, tendon, and bursa. It is characterized by calcification of the cartilage and is called pseudogout during an acute attack. The clinical manifestations of calcium pyrophosphate deposition disease are diverse, and the incidence increases with age, so it is of great significance to accurately diagnose it. Ryan-McCarty diagnostic criteria are currently the most widely used, including the presence of calcium pyrophosphate crystals in synovial fluid analysis and typical cartilage calcification under imaging. The application of musculoskeletal ultrasound has increased the sensitivity and specificity of diagnosis. This article reviews the application value of ultrasound in calcium pyrophosphate deposition disease.
