MRI对脊髓空洞症合并夏科氏关节病的诊断价值

MRI diagnosis of Charcot arthropathy caused by syringomyelia

目的探讨MRI在脊髓空洞症合并夏科氏关节病诊断中的价值,提高对该病的认识。方法回顾性分析经临床确诊的5例脊髓空洞症继发夏科氏关节病的MRI影像表现。结果 5例夏科氏关节累及肩关节3例,肘关节2例。其中3例为吸收与增生混合型,1例为吸收型,1例为增生型。MRI不仅显示受累关节骨端骨质吸收、增生硬化、游离骨块、关节变形及关节脱位,还可以清晰显示关节囊松弛、不均匀肥厚、周围软组织肿胀,关节腔积液,关节不稳造成肌腱、韧带的损伤。此外,颈椎MRI能准确诊断脊髓空洞,为夏科氏关节病提供良好的诊断依据。结论 MRI可以作为诊断脊髓空洞症继发夏科氏关节病的首选检查方法。

Objective To explore the clinical value of MRI diagnosis of Charcot arthropathy caused by syringomyelia , in order to improve the recognition of the disease .Methods 5 patients with Charcot arthropathy caused by syringomyelia were included in this study.All patients underwent MRI examination .Results Three cases of shoulder and two cases of elbow Charcot arthropathy were included.Three cases showed bone absorption mixed with hyperplasia , one case showed absorption , and one case showed hyperplasia .MRI showed bone absorption , bone hyperplasia , free bone fragment , deformation of the joint , and joint dislocation , and can also show the joint capsule relaxation , uneven hypertrophy and surrounding soft tissue swelling , joint effusion , the tendon and ligament damage by joint instability .In addition, cervical spine MRI can accurately diagnose syringomyelia , which provide good diagnostic basis for Charcot arthropathy .Conclusion MRI could be used as an optimal modality for evaluating Charcot ar-thropathy caused by syringomyelia .
