长管状骨非典型骨髓炎与骨肿瘤的X线鉴别

Radiological Differentiation of Atypical Osteomyelitis from Tumors in Long Tubular Bones

笔者通过７７例骨髓炎与表现相似的良、恶性骨肿瘤Ｘ线片对比分析，提出：表现为局部皮质梭形增厚、皮质浸润性破坏伴不规则或分层状骨膜增生而死骨不显著的骨髓炎易误为骨肿瘤；表现为局限性破坏腔的病例，可将骨髓炎误为骨肿瘤或反之。文中讨论了误诊原因，并提出两者的Ｘ线鉴别。

By detaied analysis of the X-ray findings of 77 cases of osteomyelitis and compared with a variety of benign and malignant tumors in long tubular bones, the authors found that :(1)Osteomyelitis with localized fusiform cortical thickening,irregular or lamellated periosteal reaction without obvious sequestration was apt to be misdiagnosed as bone tumors;(2)Osteomyelitis with localized destruction alone might also be misinterpreted as bone tumor or the reverse. Based on these facts, the authors discussed the factors related with the miediagnosis and the differential points of these conditions.
