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 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MR I资料,9例(10个病灶)经随访观察1~4年,2例(2个病灶)手术病理证实。对其资料进行回顾性分析。结果 26例共29个病灶,其中股骨远侧干骺部14个,胫骨近侧干骺部7个,胫骨骨干4个,股骨近侧干骺部3个,肱骨近侧干骺部1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4个病灶无改变,4个病灶稍有缩小,1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、MR I比平片更有价值。Objective To evaluate Imaging Appearance and clinical research value of fibrous cortical defect(FCD).Methods 26 cases(29 lesions) with fibrous cortical defect were examined with radiography,and CT scan was performed in 12 cases(13 lesions),and MRI scan was performed in 3 cases(4 lesions),9 cases(10 lesions)were followed up for 1～4 years.2 cases(2 lesions) were proved by operation and pathology.Results Total 29 lesions were found in 26 cases,of which the lesion was located at distal metaphysis of femar in 14...
