摘　　要：目的 探讨骨恶性纤维组织细胞病的影像学表现及诊断。方法 28例经病理检查证实的骨原发性恶性纤维组织细胞瘤影像学表现进行回顾性分析。结果 19例位于长骨干骺端,其中股骨10例,胫骨6例;15例X线表现偏心性溶骨性改变;23例CT表现为边界清楚的结节状略低密度软组织密度肿块;25例病灶强化不明显;28例MRI表现边界清楚软组织密度肿块,23例T_1加权像呈不均匀中等信号,T_2加权像呈高信号;24例病灶强化不明显。讨论 CT、MRI强化不明显对骨原发性恶性纤维组织细胞瘤的诊断具有相对特异性。Objective To explore the image manifestation and diagnosis of primary malignant fibrous histocytoma of bone Methods The image manifestation of 28 cases verified by pathology were retrospectively reviewed and analysed. Results 19 cases were occurred within the metaphysis of long bone. Among them, 10 cases within thigh-bone,6 cases within shin bone. Bone dissolution on X-ray examination is in 15 cases. Tuberous soft tissue tumor with slightly low-density and clear edge is on CT scan in 23 cases,non-contrast on CT scan in 25 cases,inhomogeneous mid-signals on T1 weighted image and high-signal on T2 weighted image on MRI scan in 23 cases, non-contrast on MRI scan in 24 cases. Conclusion CT and MRI scan are relative specific variations of leisions for diagnosis.
