脊椎骨嗜酸性肉芽肿的影像学表现(附10例分析)

目的　为了提高对脊椎骨嗜酸性肉芽肿的认识。方法　回顾分析 10例手术病理证实的脊椎嗜酸性肉芽肿的X线、CT及MRI的表现。结果　椎体呈溶骨性破坏 7例 ,囊性破坏 3例 ,椎间隙不同程度变窄或消失 ,部分椎弓及椎旁软组织受累。结论　椎体破坏与椎弓受累、椎间隙改变及椎旁软组织肿块不成比例 ,破坏区内可残存小骨碎片而无死骨存在等 ,可作为脊椎骨嗜酸性肉芽肿的主要特征表现

Imaging Findings of Vertebral Eosinophilic Granuloma(An Analysis of 10 Cases)

Objective To improve the understanding of the radioactive charcteristics of vertebral eosinophilic granuloma.Methods The imaging features (X-ray?CT and MRI) of 10 cases with vertebral eosinophilic granuloma were retrospectively analyzed.Diagnoses of all the patients had been confirmed with pathlolgical examination after operation.Results All the patients had vertebral body damages,7 with osteolytic damages and 3 with cystic damages.Intervertebral crevice became narrowing or disappearing .Some vertebral appendix and paravertebral soft tissue were involved.Conclusion It is out of proportion among the vertebral body damages,the involved vertedral arch,the changes of intervertebral crevice and the mass of paravertebral soft tissue.The remaining bone fragment without sequestrum in the damage ares is considered as the main characteristic expression of vertebral eosinophilic granuloma.
