摘　　要：目的 :探讨纤维性骨皮质缺损 (FCD)的X线诊断价值及特征表现。方法 :回顾性分析 2 7例 31处经临床、X线或手术病理证实的FCD的临床及X线表现。所有病例均有正侧位X线照片 ,14例有切线位X线照片 ,6例曾做放大摄影检查。结果 :发病部位 :股骨远侧干骺端 2 5例 2 9处 ,胫骨近侧干骺端 2例 2处 ,共 31处缺损 ;双侧发病者 2例 ,单侧发病者 2 5例 ,单侧发病者右侧 (18/ 2 3)多于左侧 (7/ 2 5 )。X线表现 :囊状骨皮质缺损 15例 17处 ,骨皮质表层不规则凹陷 12例14处 ,无膨胀性改变者 ;病变区内见云絮状密度增高 7例 ,砂粒状和斑点状或条片状钙化影 4例 ,纵向骨性间隔 2例 ,大小不等蜂窝状 2例 ;2 1例 (2 3处 )病灶边缘清晰、周围有薄层硬化缘 ,6例 (8处 )无或仅有部分较淡的硬化缘。结论 :FCD是由于局部骨膜化骨障碍而引起的骨皮质生长缺陷 ,最好发于生长期儿童 (尤以 6～ 10岁多见 )的长骨干骺端 ,尤其是股骨远端。X线能明确FCD的发病部位、大小、侵及范围 ,并能反映其病理结构特点 ,对临床诊断及治疗具有指导价值。Objective:To evaluate X-ray diagnostic value and characteristic findings of fibrous cortical defect (FCD) of bone.Methods:5'BZClinical and X-ray findings of 31 defects in 27 patients with FCD by clinical,X-ray or pathology were analyzed retrospectively.19 males and 8 females ranged in age from 6 to 24 years (21 cases between 6～10 years).All patients had anteroposterior and lateral radiograph,14 patients had tangential radiograph and 6 had magnification radiography.X-ray diagnosis of fibrous cortical bone defect(analysis of 27 cases)$$$$ TIAN Zhao-jian,MENG Xiang-qi.Department of Radiology,Shengli Oil-feild Central Hospital,Dongying 257034,China AbstractObjective:To evaluate X-ray diagnostic value and characteristic findings of fibrous cortical defect (FCD) of bone.Methods:5'BZClinical and X-ray findings of 31 defects in 27 patients with FCD by clinical,X-ray or pathology were analyzed retrospectively.19 males and 8 females ranged in age from 6 to 24 years (21 cases between 6～10 years).All patients had anteroposterior and lateral radiograph,14 patients had tangential radiograph and 6 had magnification radiography.[WTResults:Site of the 27 cases (31 defects) of FCD, 25 (29 defects) occurred in distal femur and 2 (2 defects) in proximal tibia.There were bilateral defects 2 cases and unilateral defects 25 cases. When the defect were unilateral, the right (18/25) was more than the left (7/25). X-ray manifestations included: cystic change 15 cases (17 defects ),irregular concave defect change 12 cases (14 defects ),no expansive changes.Cloudy dense areas 7 cases, sandy and spotty dense areas of striped calcifications 4 cases. 21 ( 23 defects ) edge clearly and a thin sclerosis around it, 6 (8 defects) no or only a portion of the light sclerois.Conclusion:FCD believed to be a local disturbance of cortical growth due to faulty ossification of the local periostium.The abnormality is commonly seen at the metaphyseal cortex of a long bone, specially in distal femur,in young children in the groing periode specially be
