摘　　要：目的：针对骨巨细胞瘤（GCT）的常见以及典型的CT和MRI的临床表现进行分析。方法选择2011年1月-2013年1月汕头市中心医院经过病理证实并且接受治疗的80例患者（其中CT资料32例、MRI资料48例）的病历资料回顾分析，拥有超过65%的病例表现可以被定为常见临床表现，又有所有病例的常见临床表现被定义为典型表现。结果骨细胞瘤较为常见的CT表现为：长骨骨端骨性骨质遭到偏心性溶胀破坏，在关节面之下，软组织的密度较为密集，没有钙化现象；挂边缘清晰可见，出现完全或是不完全的硬化边缘，未见骨膜反应。以上常见的CT表现的病例有20/32例，占62.5%。较为常见的MRI为：长骨骨端骨性骨质遭到偏心性溶胀破坏，在关节面之下，有不平衡信号，囊变坏死，扫描的不均匀有所增强；边缘出现低信号环，附件可见骨髓水肿，边骨没有软组织的肿块。以上常见的MRI表现的病例有23/48例，占47.9%。结论对于GCT在CT及MRI的临床表现具备很重要的诊断价值；典型的CT及MRI的临床表现不常见，诊断过程不用过分强调。Objective To analyse clinical manifestations of Common MRI and CT signs and Typical Cases of Giant cell tumor of bone（GCT）. Methods CT（32 cases） and MRT （48 cases） imaging of 80 patients from January 2001 to January 2013 with GCT confirmed by pathology were analysed retrospectively,the common signs were defined as this signs was detected in more than 65%cases.The typical cases were the cases with all the common features. Results The common CT signs included：eccentric osteolytic expansile destruction of bone in the end of long tubular bone,the soft tissue density was high under the joint surface,without calcification;smoothing border lines ,without periosteal reaction.All the forementioned common CT signs were appeared in 20 cases （62.5%）. The common MRI signs included：eccentric osteolytic expansile destruction of bone in the end of long tubular bone,there were miscellaneous signals under the joint surface,liquefy and necrosis,inhomogenerous enhancement;with hypointensity signalmargin and edema ,no soft tissue mass.All the forementioned common MRI signs were appeared in 23 cases（47.9%）.Conclusion The common CT and MRI signs are very valuable in the diagnosis of GCT. Cases with typical CT or MRI signs are not common, which should not be excessively emphasized in diagnosis and differential diagnosis.
