目的 探讨痛风性关节炎的超声表现特征。方法 分析22例临床确诊的痛风性关节炎且曾有急性痛风发作的32个受累关节的超声表现。 结果 受累关节共32个:第一跖趾关节28个(28/32,87.50%),膝关节2个(2/32,6.25%),踝关节1个(1/32,3.13%),肘关节1个(1/32,3.13%)。所有受累关节均有超声阳性表现。超声表现:关节积液30个(30/32,93.75%),滑膜增生16个(16/32,50.00%),骨侵蚀10个(10/32,31.25%),关节软骨"双边征"25个(25/32,78.13%),关节液内"暴雪样"回声10个(10/32,31.25%),关节内点状强回声8个(8/32,25.00%),关节内片状强回声团伴声影15个(15/32,46.88%),关节旁肌腱周围强回声8个(8/32,25.00%),关节周围滑囊积液4个(4/32,12.50%)。 结论 痛风性关节炎在高频超声下有多种表现,且部分超声表现具有特异性。高频超声可作为诊断痛风性关节炎的重要影像学方法。
Objective To explore the ultrasonographic features of gouty arthritis. Methods Sonographic manifestations of 32 joints with acute gout attack in 22 gouty arthritis patients were analyzed. Results Thirty-two involved joints included 28 first metatarsophalangeal joints (28/32, 87.50%), 2 knee joints (2/32, 6.25%), 1 ankle joint (1/32, 3.13%) and 1 elbow joint (1/32, 3.13%). Sonographic positive performance were found in all the involved joints, including effusion in 30 joints (30/32, 93.75%), synovial hypertrophy in 16 joints (16/32, 50.00%), bony erosion in 10 joints (10/32, 31.25%), double contour sign of articular cartilage in 25 joints (25/32, 78.13%), snowstorm appearance of the joint fluid in 10 joints (10/32, 31.25%), hyperechoic spots in 8 joints (8/32, 25.00%), intraarticular patchy hyperechogenicity with posterior acoustic shadow in 15 joints (15/32, 46.88%), hyperechogenicity around the periarticular tendon in 8 joints (8/32, 25.00%) and effusion in periarticular synovial bursa in 4 joints (4/32, 12.50%). Conclusion Gouty arthritis has multiple high-frequency ultrasonographic representations, some of them are specific.High-frequency ultrasound can be used as an important imaging technique for detection of gouty arthritis.
