摘要
目的:回顾性分析了19例经病理证实的骨内腱鞘囊肿病例的影像学资料,以提高骨内腱鞘囊肿的影像学诊断正确率。材料和方法:本组19例做了CT扫描检查,其中5例做了三维重建;所有病例均经手术病理检查证实。结果:19例,共25个病灶,15例为单发性,4例为多发性,其中1例为双侧对称性。病灶位于关节软骨下,低密度,边缘可有硬化,骨皮质可有断裂,三维重建显示病灶与关节腔相通。结论:骨内腱鞘囊肿的CT特征为:邻近关节面的圆形或不规则的单发或多发性骨质缺损,有间隔,边缘硬化,境界清晰。
In order to improve the imaging diagnositic accuracy, the imaging data （CT） of intraosseous ganglia in 19 cases were retrospectively analyzed. Materials and Methods： All of the 19 cases went to hospital because of ache and functional obstacles. All of the 19 of which have been given CT. All cases have been proved by histopathology.Results： In CT. the erosions show round or irregular mass, with internal partition （8/19）, sclerosis edge （15/19） or part - sclerosis （4/19）, broken cortex （12/19）, intact - cortex （7/19）, and without soft tissue mass and periosteal reaction （ 19/19）. Conclusion： The CT Characteristics of the ganglion would be including well - defined sclerotic rim, internal partition and broken - cortex which enclosed joints.
