骨嗜酸性肉芽肿影像学诊断及误诊分析

Imaging Diagnosis of Bone Eosinophilic Granuloma and Analyses of Misdiagnosis

目的:探讨骨嗜酸性肉芽肿的影像学特征。方法:回顾分析经病理证实的17例骨嗜酸性肉芽肿影像学资料,X线平片检查17例,CT检查9例,MRI检查4例。结果:长骨6例,椎体5例,颅骨3例,锁骨2例,髂骨1例,病灶表现为圆形、类圆形边界清楚的骨质破坏或不规则溶骨性骨破坏,伴骨膜反应及软组织肿块。结论:骨嗜酸性肉芽肿的各种影像学检查都有一定特征,结合临床资料可以提高诊断。

Objective： To inverstigate the imaging features of eosinophilic granuloma of bone.Methods：Imaging findings,including plain film（n=17）,CT scans（n=9） and MRI（n=4）,in 17 patients with pathologically-confirmed bone eosinophilic granuloma were retrospectively analyzed.Results：Of 17 cases,the lesion was located in the long-bone（n=6）,in vertebra（n=5）,in skull（n=3）,in the clavicle（n=2）,and one case in the ilium,the lesion demonstrated well define bony destruction or irregular bony destruction,with periosteal reaction and soft tissuemas.Conclusion：Imaging findings of bone eosinophilic granuloma have some characteristics,associated with clinic data could suggest the diagnosis.
