儿童脊柱嗜酸性肉芽肿的CT、MRI表现

CT and MRI Fingdings of Vertebral Eosinophilic Granuloma in Children

目的:探讨儿童脊柱嗜酸性肉芽肿(eosinophilic granuloma,EG)的CT、MRI表现。材料和方法:回顾性分析18例经手术病理证实的儿童脊椎EG的CT及MRI的表现。结果:发生于颈椎3例、胸椎7例和腰椎8例。CT表现:18例椎体不同程度溶骨性破坏,边缘不规则,椎弓根等附件破坏2例,出现周围软组织肿块3例。MRI表现:椎体骨质破坏T1WI呈等信号和T2WI呈稍高信号。椎间隙轻度变窄2例、周围软组织肿胀4例和椎弓根受累4例。结论:CT和MRI均能准确显示病变范围、结构及邻近组织改变,大多数病例能正确诊断,但MRI优于CT。

Purpose： To evaluate CT and MRI manifestations of vertebral eosinophilc granuloma in children. Materials and Methods： The CT and MRI findings of 18 cases with vertebral eosinophilic granuloma proved by pathology were retrospectively analyzed. Results： In all the 18 children, the lesion involved cervical spine in 3 cases, thoracic spine in 7 cases, and lumbar spine in 8 cases. On CT, lesions presented as irregular or wedge-shaped osteolytic bone destruction, involved appendix in 2 cases and paravertebral soft tissue in 3 cases. On MRI, lesions presented as isointensity on T1WI and hyperintensity on T2WI, involved appendix and paravertebral soft tissue in 4 cases. Conclusion ： Both CT and MRI can make a correct diagnosis in most cases of children＇ s vertebral eosinophilc granuloma, while MRI showed a little bit superior to CT.
