1、纤维性骨皮质缺损影像表现及临床探究价【摘要】目的探讨纤维性骨皮质缺损的影像表现与临床研究价值。方法回顾性分析26例（29个病灶）均有平片资料其中12例（13个病灶）有CT资料，3例（4个病灶）有MRI资料,9例（10个病灶）经随访观察1-4年，2例手术病理证实。结果26例共29个病灶，其中股骨远侧干飯部14个，胫骨近侧干飯部7个，胫骨骨干4个，股骨近侧干飯部3个，肱骨近侧干飯部2个;单发19例，多发7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,周围未见骨膜反应及软组织肿胀。13个
2、病灶CT表现:缺损可位于骨皮质表层（9个）或骨皮质内（4个）,位于骨皮质表层者缺损表面无骨壳，局限于骨皮质内者缺损表面骨壳可完整；7个病灶凹向髓腔并以硬化边与髓腔分隔,但无膨胀性改变或突入髓腔;灶内为均匀软组织密度,未见钙化灶。9个病灶经随访观察，其中3个病灶无改变,3个病灶稍有缩小,2个病灶发展为非骨化性纤维瘤。结论典型的纤维性骨皮质缺损单凭平片即可诊断，但CT、MRI比平片更有价值。【关键词】纤维性骨皮质缺损；骨骼；X线计算机，放射摄影术中图分类号:R814文献标识码：A文章编号:1005-0515(2010)02-001-03I
