1、痛风性关节炎的超声表现曹君妍任杰黄冬梅郑荣琴王巧缘[摘要]目的探讨痛风性关节炎的超声特征。方法对确诊的5例痛风性关节炎患者19个病变关节的超声表现进行回顾性分析，总结痛风性关节炎的声像图特点。结果19个关节中第一跖趾关节5个，膝关节8个，踝关节、肘关节、腕关节各2个。17个(89.4％)关节超声表现为软骨表面回声增强，与深面的骨性关节面强回声线形成“双边征”。13个(68.4％)关节表现为不同程度的关节腔积液，积液内可见漂浮点状强回声，振动后运动明显。11个(57.9％)关节内见滑膜增厚，彩色多普勒显示滑膜内部血流信号丰富或稀少
2、。其中1例膝关节髌上囊处滑膜呈结节状明显增厚，范围约5cm×2cm，内见大量强回声点，后方伴声影。6个(31.6％)关节软骨超声表现为不规则形变薄，软骨下骨面粗糙、回声中断。4个(21.1％)关节周围软组织见稍高或强回声团，后伴或不伴声影。其中3个关节同时出现邻近骨皮质回声毛糙不平滑、连续性中断或缺损。结论痛风性关节炎具有一定的超声表现，超声可能早期提示此病，具有一定的临床应用价值。超声检查；关节炎，痛风性UltrasonographicfindingsingoutyarthritisCAOJun-yanRENJieHUANGD
