纤维性骨皮质缺损的X线、CT诊断分析（附26例报告）

目的：探讨纤维性骨皮质缺损的影像学表现。材料与方法：对经手术病理证实、随访观察的26例纤维性骨皮质缺损影像学资料进行分析,26例（30个病灶）均有平片资料,其中18例（20个病灶）有CT资料,13例（14个病灶）经随访观察1~4年,3例经手术病理证实。重点分析X线、CT特点。结果：26例共30个病灶,其中股骨远侧干骺端15个,胫骨近侧干骺端9个,股骨近侧干骺端3个,腓骨远侧干骺端2个,胫骨骨干1个;单发22例,多发4例。X线表现：多呈类圆形或椭圆形的低密度灶,切线位呈杯口状或碟状的骨皮质缺损区,病灶内缘可见硬化边。CT表现：缺损可位于骨皮质表层或骨皮质内,位于骨皮质表层者缺损表面无骨壳,位于骨皮质内者缺损表面骨壳可完整;部分病灶凹向髓腔且硬化边与髓腔分隔,但无膨胀性改变,灶内为均匀软组织密度,未见钙化灶。14个病灶经随访观察,其中8个病灶可见不同程度缩小,3个病灶经手术治疗,3个病灶完全消失。结论：纤维性骨皮质缺损单凭平片、CT即可诊断。

The Analysis and Diagnosis of X-rays and Computerized Tomoscanning (CT) on Fibrous Cortical Defect (FCD)(26 Cases Report)

Purpose:To research the manifestation of medical image science about FCD.Materials and Methods:After the confirmation about pathology of operation and analysis about those materials,which are 26 follow-up about medical image science on FCD,we find that there are plain films about all of the 26 cases(30 hepatocellular carcinoma cesions(HCC) presented),data of CT about 18 cases(20 HCC presented),13 cases were followed up for one or several years(14 HCC presented) and 3 cases were confirmed by pathology of ope...
