摘要
目的提高对纤维骨皮质缺损(FCD)和非骨化性纤维瘤(NOF)的影像诊断和鉴别诊断水平。方法回顾性对照分析60例FCD和NOF的临床、影像学和病理学资料。结果 FCD和NOF均好发于膝关节周围骨,病理学上均为纤维组织,无成骨成分。X线和CT表现为局限于骨皮质内、骨髓腔内或位于骨皮质内偏心性膨胀累及骨髓腔,均匀软组织密度影。MRI上主要为等T1等T2异常信号。结论 FCD和NOF具有相同的好发部位和病理学表现,可视为同一病变的不同表现或不同发展阶段,影像上局限于骨皮质者为FCD,累及骨髓腔者为NOF。
Objective To improve the imaging diagnostic accuracy of Fibrous Cortical defect（FCD） and Non-ossifying Fibroma（NOF）.Methods The clinical,imaging and pathological data of the cases with FCD and NOF were reviewed,analyzed and compared.Results FCD and NOF were often located in bone around knee joint and their pathologic findings were composed of non-ossifying fibrous tissue.FCD and NOF showed limited cortical bone,the bone marrow cavity or involvement in the cortical bone and marrow cavity,uniform soft tissue density on X-ray and CT.They showed isointensity signal on MRI.Conclusion FCD and NOF have similar location and pathology results.They can be regarded as the performance of the same disease with different images or different stages of development.An intracortical lesion can be regarded as FCD,one extending into medullary cavity as NOF.
