脊柱嗜酸性肉芽肿的MRI诊断价值

MRI Diagnosis Value of Spine Eosinophilic Granuloma

目的:探讨脊柱嗜酸性肉芽肿的MRI影像学特征。方法:回顾分析经病理证实的14例脊柱嗜酸性肉芽肿MRI影像学资料。结果:单发例12例,多发2例(图A.B.C),颈椎3例,胸椎9例,腰椎2例,多发病灶均位于胸椎。病灶表现为病变椎体不同程度压缩变扁,信号异常,可伴椎体及附件骨质破坏及椎旁软组织肿块,邻近椎间盘信号未见明显异常。结论:MRI对病变范围、软组织改变及周围结构是否受累显示非常清楚,脊柱嗜酸性肉芽肿的MRI影像学检查有一定特征,结合临床资料可以提高诊断。

Objective： To discuss the magnetic resonance imaging features of eosinophilic granuloma in spine. Methods： Retrospectively analyzed MRI features of 14 eosinophilic granuloma in spine proved by pathology. Results： 12 lesions are single,2 are multiple. 3 lesions are located in cevical vertebe, 9 in thoracic vertebe and 2 in lumber vertebre. Multiple lesions are all located in thoracic vertebe. The involved vertebres were compressed and show abnormal signal, accompanied by bone destruction and soft mass in vertebre and appendix, the adjacent intervetebre disc were normal. Conclusion： MRI can demonstrate the extent of the disease, soft tissue and surrounding structures clearly. MRI findings are characteristic in some respect. It is possible to improve the diagnostic accuracy by MRI and clinical findings.
