【摘要】 目的　分析骨巨细胞瘤的CT征象。方法　回顾性分析 42例经手术病理证实的骨巨细胞瘤的CT表现。结果　 ( 1)骨巨细胞瘤骨质破坏有囊样膨胀性破坏和单纯溶骨性破坏两类 ,前者占多数 ;( 2 )病灶内多数无骨性分隔 ( 4 0 /42 ,95 .2 % ) ;( 3)多数病灶内可见骨嵴 ( 6 3 .2 % ) ;( 4 ) 44 .7%的病例存在完整或不完整的硬化边 ;( 5 )骨内软组织密度多不均匀 ,其中 5例 ( 11.9% )出现液 -液平面 ;( 6 )骨外软组织肿块多出现在骨壳断续或不完整的病例。结论　CT可以加深对骨巨细胞瘤的认识 ,丰富其影像学征象 ,提高对该肿瘤的诊断及鉴别诊断的能力。更多还原

【Abstract】 Objective To analyse CT signs of giant cell tumor of bone.Methods CT appearances of 42 cases of giant cell tumor of bone were reviewed.All patients were pathological proven.Results (1)Two kinds of bone destruction were seen in all ases:expansive cystic destruction and osteolytic destruction.The anterior was predominantly.(2)Most of our patients haven’t bone septations in their tumors (95.2%).(3)Bone crests were usually seen in our study(63.2%).(4)Complete or incomplete sclerotic borders existed in 44.7% of all cases.(5)The inner bone soft tissues were heterogeneously in most of the patients.Fluid-fluid level can be seen in 5 cases (11.9%).(6)The outer-bone soft tissue masses were demonstrated in the majority cases with discontinuous bone shell.Conclusion CT may deepen our understanding and add imaging signs about giant cell tumor of bone;Which can enhance our diagnostic and differential diagnostic capability.更多还原
