摘　　要：目的分析单发型长骨内生软骨瘤的X线及CT表现,探讨X线、CT的诊断价值。方法回顾性分析经手术病理证实的单发型长骨内生软骨瘤16例,所有病例均行X线及CT检查,分析比较X线和CT对骨质改变及病灶钙化的显示能力。结果 X线和CT检查分别有11例和16例可见骨质破坏;清楚显示灶内钙化分别有9例及16例;恰当的CT后处理技术有助于显示病灶全貌。结论 X线空间分辨力高,是单发型长骨内生软骨瘤首选检查方法,CT作为X线的补充。四肢长骨囊状膨胀性骨质破坏,内有不同程度的钙化是内生软骨瘤的重要征象,CT对这些征象敏感性较平片高,对临床怀疑而平片难以确诊的病变,CT检查有较高的价值,可为单发型长骨内生软骨瘤的诊断和鉴别诊断提供重要依据。Objective To evaluate the features and diagnostic value of X-ray and CT on solitary enchondroma in long bone.Methods 16 cases of solitary enchondroma in long bone proved by surgical pathology were studied retrospectively.All patients had been taken plain X-ray film and CT scan.The displayed ability of destructive bone and calcifications between X-ray film and CT scan were analyzed.Results Of these patients,11 cases showed destruction of bone on X-ray film and 16 cases showed such changes on CT scan.9 cases showed calcifications inside the lesion on X-ray film clearly while 16 cases on CT.Pertinent CT post-processing techniques helped to show the whole picture of lesions.Conclusion X-ray film is the first choice to diagnose solitary enchondroma in long bone for its high spatial resolution.CT is the supplementary method of it.The cryptomere and expansivity destruction of long bone,and different degree of calcification were the important sign of this tumor.CT has higher sensitivity than X-ray film for these signs.It can provide important evidence to the diagnosis and differential diagnosis of solitary enchondroma in long bone.
