骨原发恶性纤维组织细胞瘤的影像诊断(附8例报告)

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。

Imaging Diagnosis of Primary Malignant Fibrous Histiocytoma of Bone(A Report of 8 Cases)

Objective To analyze the imaging features and its value in diagnosing primary malignant fibrous histiocytoma(MFH) of bone.Methods Imaging features(X-ray,CT,MRI) in 8 cases of MFH confirmed pathologically,and were retrospectively reviewed.Results The location of lesions in 6 cases was in upper femur,2 cases was in upper tibilar.Worm-eaten-like bone destruction withindistinct margin was presented on X-ray film,some lesions showed slightly marginal sclerosis.Tumors were soft tissue density on CT(CT value was 34~35 HU).The masses of soft tissue were showed much distinct.Conclusion The primary MFH of bone is not of characteristic imaging findings.It can improve obviously the diagnosis of the disease by the comprehensive analysis of the imaging data.
