目的 :为提高骨原发性恶性纤维组织细胞瘤的临床 X线诊断水平。方法 :回顾性分析 18例经手术和病理证实的本病临床 X线所见。结果 :骨破坏大而症状轻 ,好发长骨干骺端或骨端。主要骨改变有散在性斑片状或大片溶骨性破坏 ;单囊或多囊状轻度膨胀性破坏 ;大片或囊状骨破坏区内伴有多发小孔状破坏。一些病例破坏区见条状或网状骨嵴或 /和斑点状钙化影 ,破坏缘不但模糊不清 ,而且有类似良性瘤的清楚或锐利的边缘 ,伴轻度硬化 ,无骨膜反应或有轻度反应。结论 :本病的 X线表现多样性 ,诊断需结合临床

The Clinic-Radiologic Analysis of Primary Malignant Fibrous Histiocytoma of Bone(A Report of 18 Cases)

Objective:To improve the clinic-radiologic diagnostic accuracy of primary malignant fibrous histiocytoma(MFH)of bone.Methods:The authors retrospectively analyzed clinic-radiologic findings of 18 cases with primary MFH of bone confirmed by surgery and pathology.Results:Destructiove area of bone was rather larger,howerver,clinical symptom was not serious.Tumor frequently located in the metaphyses or the ends of long bone.The main osseous changes included scattered patchy or massive osteolytic destruction,a single cystic or multi-cystic destruction with slight expansive change and multiple small cystic changes in a massive lytic area or a large cystic lytic area.Coarse trabeculation/or dot-like calcifications could be seen in destructive area in some instance.The margins of destructive area were not only ill defined with malignant appearance,but also well-defined or sharp and slight sclerosis with benign-looking appearance.The periosteal reactions was slight or completely lacking.Conclusion:The X-ray features of MFH are varied,its diagnosis has to combine with clinical data.
