目的分析骨原发恶性纤维组织细胞瘤(MFH)的影像学表现,评价其影像学诊断价值。方法回顾分析8例经过手术证实的骨原发恶性纤维组织细胞瘤的X线平片、CT及MR I表现。结果病变发生于股骨上端6例,胫骨上端2例。病变在X线平片上呈溶冰样破坏,边界不清,部分有轻度硬化边。在CT上其内可见软组织密度影,CT值在34~45 HU左右,而MR I图像上则可见明显软组织肿块影,周围软组织改变更清楚。结论骨原发恶性纤维组织细胞瘤的影像表现缺乏特异性,但通过各种影像资料的综合分析,可以明显提高对本病的诊断水平。

Objective To analyze the imaging findings of primary malignant fibrous histiocytoma (MFH) and evaluate its imaging diagnostic value. Methods Eight cases of primary malignant fibrous histiocytoma confirmed by surgery were retrospectively analyzed by X - ray, CT and MRI. Results The lesions occurred in 6 cases of upper femur and 2 cases of upper tibia. Lesions on the X-ray film was ice-like destruction, the border is unclear, some mild hardening edge. The soft tissue density was seen inside CT, the CT value was about 34-45 HU, while the obvious soft tissue mass was seen on the MRI image, and the changes of the surrounding soft tissue were clearer. Conclusion The imaging findings of primary malignant fibrous histiocytoma are not specific. However, the comprehensive diagnosis of various malignant fibrous histiocytomas can significantly improve the diagnosis of this disease.
