目的 :讨论骨嗜酸性肉芽肿的放射学特征。方法 :回顾分析经病理证实的 2 8例骨嗜酸性肉芽肿的X线、CT资料。结果 :本病基本表现相似 ,但不同病期、不同部位及不同年龄其放射学特征变化较大。CT对病变范围、皮质、骨膜、软组织改变、死骨及邻近结构受累与否显示更清楚。结论 :X线平片是诊断本病主要方法 ,CT能获得骨骼软组织解剖及病理结构细节 ,对复杂骨价值更大。 Objective: To discuss the radiological features of bone eosinophilic granuloma. Methods: The X-ray and CT data of 28 cases with eosinophilic granuloma confirmed by pathology were retrospectively analyzed. Results: The basic performance of the disease similar, but different stages, different parts and different age radiographic features larger changes. CT of the lesion, cortex, periosteum, soft tissue changes, sequestrum and adjacent structures involved or not show more clearly. Conclusion: X-ray is the main method to diagnose this disease. CT can obtain anatomical and pathological structure details of skeletal soft tissue, which is of great value to complex bones.
