目的探讨骨嗜酸性肉芽肿的临 床、病理和影像学表现，以提高对本病 的认识。方法 回顾性分析17例经病理证 实的骨嗜酸性肉芽肿的影像学特征。结 果 17例中，单发者16例，多发者1例。 单发者中颅骨6例，长骨4例，骨盆3例， 脊柱3例。多发者累及锁骨和脊柱。主要 影像学表现为骨质破坏、邻近骨皮质改 变、骨膜增生、软组织肿胀和肿块。术 前诊断正确9例，误诊8例。结论 骨嗜酸 性肉芽肿的影像学表现有一定的特征， 综合分析可以提高对本病的诊断水平， 最终确诊需病理检查。

Objective To explore the radiologic features of ensinophilic granuloma of bone and improve the value of imaging to the disease. Methods the radiologic features of 17cases with ensinophilic granuloma of bone as confirmed by operation and pathology were studied retrospectively. Results There were 16 cases who had single lesion and the other had multiple lesions. Among 16 cases who had single lesion, 6 cases were located in crinial bone, 4 cases in long bone, 3 cases in pelvis, 3 cases in vertebral column. The imaging characteristics included the bone destruction, the changes of cortical bone, periosteal proliferation and soft-tissue swelling or mass. 9 cases were diagnosed correctly. 8 cases were misdiagnosed. Conclusion The radiologic appearances of ensinophilic granuloma of bone have relative characteristics, which is helpful for the diagnosis of this disease, yet the final diagnosis still depends on pathology.
