摘　　要：目的探讨骨纤维异常增殖症(FDB)的影像学表现及病理特征。资料与方法搜集经临床手术或病理证实的FDB21例,所有病例均行X线检查,5例行CT检查,2例行MRI检查并行增强扫描。结果单发型16例,多发型5例。其中下肢骨10例(11块),面颅骨5例(8块),上肢骨4例(4块),骨盆1例(4块),肋骨1例(4根)。X线平片和CT像上表现囊状改变13例,磨玻璃样改变5例,丝瓜络状改变2例,虫蚀状改变1例;MRT1WI病灶为低信号,T2WI可为低、中、高信号。结论多种影像学检查方法对FDB的诊断各有优缺点,可互为补充。Objective To discuss imaging diagnosis of FDB and its pathological features. Materials and Methods 21 cases with FDB proved surgically and pathologically were examined with X plain film, 5 with CT and 2 with plain and contrast MRI. Results There were 16 cases with single FDB and 5 cases with palyostotic FDB. Among them 10 cases of lesions located in lower limbs, 5 in cranioficial bones, 4 in upper limbs, 1 in pelvis and 1 in ribs respectively. X-ray and CT showed the following features of the lesions： 13 cases with sacciform images, 5 with frosted glass form images, 2 with vegetable sponge images and 1 with insect biting form images; All cases were appeared as hypaintensity on T1WI and variable intensity on T2WI. Conclusion All imaging techniques have their own advantage and can be used reciprocally.
