骨良性纤维组织细胞瘤的影像学表现(附4例报道及文献复习)

Imaging findings of bone benign fibrous histiocytoma(a report of 4 cases and review of the literature)

目的:探讨骨良性纤维组织细胞瘤的影像学特点,以提高对该病的影像学诊断水平及鉴别诊断能力。方法:收集4例骨良性纤维组织细胞瘤患者的临床及影像学资料,结合近年来国内外相关文献进行回顾性分析。结果:4例骨良性纤维组织细胞瘤均表现为类圆形或椭圆形骨质破坏区,边界清楚,有完整硬化环,环壁厚薄较均匀,无骨膜反应。2例为多发病变,病变累及双侧股骨及髂骨;2例MRI检查T1WI等信号,T2WI不均匀高信号,其中1例病变周围可见软组织肿块;1例CR及CT检查提示病灶内有骨性分隔和软组织密度影。结论:骨良性纤维组织细胞瘤影像学上具有一定特异性。

Objective ：To explore the radiographic features of bone benign fibrous histiocytomas （BFH） so as to improve the reognition and diffemtial diagnosis of bone BFH. Methods：The clinical and radiographic data of 4 patients with BFH were analyzed retrospectively, and relevant literatures were reviewed. Results：All of the 4 cases appeared as round or ellipse destruction of bone, clear boundary, complete rim of sclerosis and uniformly thickness of wall, but without periosteal reaction. 2 cases were multi - lesions, which involved the bilateral femoral and flank bone; 2 case were shown isointense in T1WI and heterogeneous hyperintense in T2WI, and one of which with peripheral soft tissular mass in MR images ; 1 case was shown bony septation and soft tissular density in CR and CT images. Conclusion： Imaging findings of bone BFH have some characteristics, which are helpful for diagnosis and differential diagnosis.
