骨嗜酸性肉芽肿的放射学特点

Radiologic Characteristics of Eosinophilic Granuloma of Bone

目的 讨论骨嗜酸性肉芽肿的影像学特征。方法 回顾分析经手术病理证实的 3 0例骨嗜酸性肉芽肿的临床及影像学资料。结果 单发 2 5例 (2 5 / 3 0 )占 83 .3 % ,多发 5例 (5 / 3 0 )占 16.7%。本病多发于儿童和青少年 ,其骨破坏的影像学征象因部位不同而异 ,本病具有骨破坏明显而临床症状较轻的特点。结论 X线平片是诊断本病的主要方法。CT及MRI对病变范围 ,软组织改变 ,邻近结构受累情况显示更清楚。

Objective To discuss the imaging features of bone eosinophilic granuloma. Methods The imaging appearances of 30 patients with bone eosinophilic granuloma confirmed by pathology after operation were reviewed retrospectively. Results Monofocal lesion was found in 25 cases (83.3%) and multifocal lesions were in 5 cases (16.7%). The disease often occurred in children and adolescence. According to the location, their radiographic characteristics of bone destruction appeared different. However, the disease always showed serious bone destruction, few clinical signs and symptoms. Conclusion Routine radiography is the main methods in diagnosis of bone eosinophilic granuloma. CT and MRI could clearly demonstrate the extent of bone involved, and the change of soft tissue.
