【摘要】 目的探讨非骨化性纤维瘤的X线及CT诊断及鉴别诊断。方法对29例经手术病理证实的非骨化性纤维瘤的X线平片及CT表现进行分析,其中男22例,女7例,年龄5~59岁,平均21.3岁。29例均做X线平片检查,12例做CT检查。结果发生于长骨27例,其中位于干骺端17例,骨干2例,骨端8例,另2例发生于不规则骨坐骨、椎体各1例。29例中病灶最大径7cm,最小径0.5 cm。病灶多沿患骨的长轴发展,病变多呈圆形或椭圆形,21例边缘有分叶,26例病灶边缘可见硬化边。X线22例有病灶内分隔,CT观察仅2例可见分隔;骨外形膨大13例;2例合并病理骨折。结论非骨化性纤维瘤X线平片及CT表现具有一定的特征性,绝大多数能术前诊断。更多还原

【Abstract】 Objective To study X-ray and CT diagnosis and Differential diagnosis of nonossifying fibroma.Methods 29 cases of nonossifying fibroma proved by pathology were included in this paper.29 cases underwent radiography and 12 cases underwent CT scan.There were 22 male and 7 female,with age ranged from 5~59 years(mean age 21.3 years),X-ray and CT findings of tumors were analysed.Results The tumors were located in long bone in 27 cases,in which 17 cases were located in metaphses,2 cases in diaphyses,8 cases in bone end and 2 cases in irregular bone.The maximum diameter of tumors ranged from 0.5~7 cm.The tumors were round,oral or mild lobular in 21 cases,the tumors were showed sclerotic borders in 26 cases.Septum was demonstrated in 22 cases on X-ray plain films,but only 2 cases on CT.Bone expansion was showed in 13 cases.Conclusion Most of nonssifying fibroma have characteristic X-ray and CT findings,the diagnosis be identified by X-ray and CT before operation.更多还原
