摘　　要：目的探讨痛风性踝关节炎的MRI表现及诊断价值。方法选取并分析41例经临床确诊的痛风患者46个踝关节的MRI资料,踝关节分为8个区域(包括内踝区、外踝区、后踝区、前踝区、胫腓下联合区、跗骨窦区、距骨头外侧区、距骨头内侧区),分析骨质侵蚀与痛风石、骨髓水肿之间的相关性。结果痛风石发生率39.9%;骨质侵蚀发生率26.4%;骨质增生发生率93.5%;关节腔积液、滑膜增厚发生率均为95.7%;133处肌腱韧带受累。骨质侵蚀与痛风石、骨髓水肿的相关性分析有统计学意义。结论MRI检查可以敏感地观察踝关节痛风石、骨质侵蚀、骨髓水肿、关节腔积液、滑膜增厚以及皮下软组织肿胀;骨质侵蚀与痛风石、骨髓水肿有明显相关性。Objective To investigate the MRI findings and diagnostic value of gouty ankle arthritis.Methods The MRI data of 46 ankles in 41 patients with clinically diagnosed gouty arthritis were retrospectively analyzed.The ankle was divided into 8 regions(including the medial malleolus region,the lateral malleolus region,the posterior malleolus region,the anterior malleolus region,the subtibiofibular joint region,the tarsal sinus region,the lateral talus region,the medial talus region),and bone erosion and tophi were analyzed the correlation between bone marrow edema.Results The incidence of tophi was 39.9%.The incidence of bone erosion was 26.4%.The incidence of hyperosteogeny was 93.5%.The incidences of joint cavity effusion and synovial thickening were 95.7%.There were 133 tendons and ligaments were involved.The correlation between bone erosion and tophi and bone marrow edema was statistically significant.Conclusion MRI examination can sensitively observe the situation of ankle tophi,bone erosion,bone marrow edema,joint cavity effusion,synovial thickening and subcutaneou soft tissue swelling.Bone erosion is significantly associated with tophi and bone marrow edema.
