骨纤维异常增殖症生长方式的影像研究

目的 探讨骨纤维异常增殖症起始部位与生长方式。分析其影像学特异性征象。方法 对13例经手术病理证实的骨纤维异常增殖症之CT/MR影像进行回顾性分析并作献复习。结果 病灶成像以纤维组织为主多局限于皮质内生长；病灶成份以编织骨为主。易穿入髓腔弥漫生长。结论 病变起始骨皮质，按病理组织学不同成份。决定其生长方式。CT/MR影像显示起始部位与发展趋势，具有特殊定性诊断价值。

Growing patterns of fibrous dysplasia: Evaluation of CT and MRI

Objective To understand the initial locations,the growing patterns and the imaging features of the fibrous dysplasia(FD)Methods Thirteen patients with surgically and pathologically proved FD underwent computed tomography(CT)and Magnetic resonance imaging(MRI)examinations.The imaging features of FD in all patients were analyzed retrospectively and correlated with related literature.Results The lesions which mainly consisting of fibrous tissue mostly located within the cortical bone,whereas the lesions in which the components mainly consisting of woven bone tend to expand into the medullary cavities and to show the diffuse growing.Conclusion The growing pattern of FD lesions which arising from the cortical bone are mainly dependent on different histopathological components in the lesions.CT and MRI examinations have special value for detecting FD because these techniques can display the initial locations and developing tendence of the FD.
