1、从MRI图像分析SAPHO综合征引起的骶髂关节变化,内科论文 内容摘要目的 回首性分析13例SAPHO综合征患者的骶髂关节MRI图像,旨在提高临床医师对此病的认识,提高诊断的准确性。材料与方式方法 纳入2020年11月至2021年8月于北京协和医院就诊的13例伴骶髂关节受累的SAPHO综合征患者,华而不实女9例,男4例,平均年龄45.9 8.9岁,总结其骶髂关节病变的影像学特征。结果 13例患者中双侧骶髂关节受累者有11例,单侧者2例,因而,共24个骶髂关节受累。16个关节以骶骨侧病变为主,20个关节病变同时累及滑膜部和韧带部。一些骶髂关节邻近骨质出现异常MRI信号,包括骨髓水肿信号16/24
2、、脂肪沉积信号24/24、骨质毁坏18/24、骨质硬化19/24 .关节间隙增宽者占8.3%2/24,关节间隙狭窄者占16.7%4/24,关节强直者占20.8%5/24。25%6/24的病变关节出现关节腔积液,8.3% 2/24的病变关节出现周边软组织水肿。结论? SAPHO综合征患者的骶髂关节病变多为双侧受累、骶骨侧病变为主,且具有新老病灶并存的特点,较少引起关节强直。上述特征可从影像学上提示SAPHO综合征,结合患者的皮肤病变,综合评估做出诊断。 本文关键词语 SAPHO综合征;骶髂关节;磁共振成像。 Abstract Objective: To retrospectively evalu
3、ate the MRI features of sacroiliacjoint SIJ disorders in 13 SAPHO patients, thus increasing the awareness of SAPHOsyndrome among clinicians and improving its diagnostic accuracy. Materials andMethods: 13 SAPHO patients with SIJ involvement female: male, 9:4; mean SDage, 45.9 8.9 years who presented
4、to Peking Union Medical College Hospitalbetween November 2020 andAugust 2021 were enrolled. MR images of the SIJs wereevaluated. Results: In our study, 11 SAPHO patients were involved with SIJ disordersbilaterally and 2 unilaterally. Therefore, a total of 24 SIJs were affected. Among theinvolved 24
5、SIJs, lesions in 16 SIJs predominantly affected the sacrum, and lesionsin 20 SIJs involved both the synovial proportion and ligamentous proportion. Severalabnormal MRI signal intensities in the bone adjacent to SIJs were detected, includingbone marrow edema16/24, fatty deposition24/24, bony erosion1
6、8/24 andsclerosis 19/24。 Joint space widening was present in 8.3%2/24 of SIJs, joint spacenarrowing in 16.7%4/24 and articular ankylosis in 20.8%5/24。 Articular effusionswere observed in 25%6/24 of SIJs. Edema in the surrounding soft tissue wasdetected in 8.3%2/24 of SIJs. Conclusion: SIJs were more
