【摘要】 目的探讨少见部位的骨软骨瘤影像表现,提高少见部位骨软骨瘤的影像诊断水平。材料与方法采用回顾性分析的方法,取经手术病理证实,或临床长期动态观察证实的少见部位骨软骨瘤病例12例;其中男性7例,女性5例,平均年龄43岁;所有病例均行X线、CT检查,7例行MR检查。对上述病例的影像学表现进行回顾性研究;总结其影像特征。结果影像特征表现为:病变发生部位:四肢长管状骨中段4例,肩胛骨4例,颅面骨2例,肋骨近端2例,所研究病例病变骨表面均表现出典型的软骨帽,骨皮质与母骨连续等影像特征;部分病例内部可见钙化,增强扫描无明显强化;病灶生长无明显方向性。结论少见部位骨软骨瘤具有某些影像特征;多数情况下,我们能通过这些特征准确诊断少见部位骨软骨瘤。更多还原

【Abstract】 Objective To probe into imaging feature,diagnosis methods about the osteochondroma grossing in unusual location.Materials and Methods The clinical and image data of 12 cases proved by operation and pathology,or clinical chronically look-in;were analyzed retrospectively(7 of males,5 of females,mean age 45).All patients were examed by X-ray and CT,besides 7 of cases had taken MR.And summarize the image characteristics of the osteochondroma.Results The unusual lacation include: the middle of extremity bone 4 cases,the scapula 4 cases,the skull bone 2 cases,the approximately rib 2 cases.All patients presented cartilage cap,and the bone cortex are connect.Conclusion There are some characteristics of image findings which are helpful to diagnose the osteochondroma in unusual location.We can distinguish the osteochondroma in unusual location in majority by these of characteristics.更多还原
