【摘要】 目的 分析脊椎骨嗜酸性肉芽肿的MRI特征。方法 回顾分析经病理证实的12例脊椎骨嗜酸性肉芽肿的MRI资料。结果 12例脊椎骨嗜酸性肉芽肿主要表现为T₁WI低或等信号,T₂WI及T₂FLAIR像为高或混杂信号,病灶周围正常骨髓内可见高信号水肿带;8例椎体呈扁平状,4例呈楔形,所有病例均形成椎旁软组织肿块,其中6例表现为“袖套征”;MRI增强椎体病变及周围软组织呈明显不均匀强化。结论 MRI对脊椎骨嗜酸性肉芽肿的诊断具有重要价值。更多还原

【Abstract】 Objective To analyze the MR manifestations of spinal eosinophilic granuloma.Methods MRI appearances of 12 patients with eosinophilic granuloma of spine confirmed by pathology were reviewed retrospectively.Results The lesions of spinal eosinophilic granuloma appeared as isointensity or hypointensity on T₁WI and hyperintensity or heterogeneous intensity on T₂WI and T₂FLAIR,with high signal intense edema around the lesions.The pathological vertebras of 8 were presented as coronary longitude,and 4 as cuneiform.All cases had perivertebral soft tissue masses and 6 cases of them showed oversleeve like.The lesions and their soft tissue masses were markedly heterogeneous enhancement after being injected of Gd-DTPA.Conclusion MRI is of great value in diagnosis of spinal eosinophilic granulomas.更多还原
