摘　　要：目的:探讨X线和CT检查在骨肿瘤样病变中的诊断价值。材料与方法:对38例经手术病理证实的骨肿瘤样病变X线和CT资料进行了回顾性分析和总结,其中单纯性骨囊肿15例,骨纤维异常增殖症12例,动脉瘤样骨囊肿6例,嗜酸细胞肉芽肿3例,甲旁亢囊性骨炎2例,38例均有X线平片资料,其中26例同时有CT检查资料。结果:本组38例中,X线平片结合病史做出正确诊断者25例,诊断准确率约66%;26例CT检查结合临床做出正确诊断者22例,诊断准确率约85%;26例具有X线平片和CT资料的病例综合诊断的准确达92%。骨囊肿表现单房性或多房性囊性病变,动脉瘤样骨囊肿表现为吹气球样改变,骨纤维结构不良表现为磨玻璃样或丝瓜瓤改变,嗜酸性肉芽肿表现为圆形或类圆形破坏,伴有硬化。甲旁亢囊性骨炎表现为骨膜下皮质吸收以及多房囊样病变。结论:骨肿瘤样病变具有其特征性的X线和CT表现,X线和CT检查各有其优缺点,综合诊断可以提高疾病的诊断准确率。Purpose： To evaluate the X- ray and CT diagnostic value of bone tumor- like lesions. Materials and Methods： 38 cases bone tumor- like lesions confimned by surgery and pathology were retrospectively analyzed, including simple bone cysts 15 cases, fibrous hyperplasia 12 cases, aneurysmal bone cyst 6 cases, eesinophilic granuloma 3 cases, hyperparathyroidism 2 cases. All cases have X- ray data, and 26 cases of them also have CT data. Results： The diagnostic accuracy rate is only about 66% through X- ray features in 38 cases and 85% throungh CT features in 26 cases respectively, but the accuracy rate can reach 92 % through both X - ray and CT features. Bone cyst shows single - or multi - room cystic lesion, aneurysms bone cyst shows balloon- like sign, fibrous dysplasia shows the grinding glass or wire -like changes,eosinophilic granuloma shows the round or round- like destruction, with sclerosis, the bone changes of hyperparathyroidism shows subperiosteal cortex absorption and the capsule-like lesions. Conclusion： The bone tumor- like lesions have their characteristic X- ray and CT findings. X - ray ,and CT scan have the advantages and disadvantages, the comprehensive diagnosis can improve diagnosis accuracy rate.
