摘要
目的:探讨软骨肉瘤的影像学诊断。方法:回顾性分析经病理证实的32例软骨肉瘤的影像学特点。32例均行X线平片检查,其中25例行CT检查,MR检查14例。结果:32例平片发现病变内钙化28例。25例做CT者均见骨质破坏和钙化影,软组织肿块21例,骨膜反应2例。MR表现:肿瘤呈等长T1长T2为主的混杂信号,可见长T1短T2信号分隔,增强扫描示分隔强化和肿块周边部强化,钙化呈长T1短T2信号。结论:骨质破坏、钙化、软组织肿块、弓环状分隔等构成软骨肉瘤的主要影像学特点,对诊断和鉴别诊断具有重要价值。
Objective:To observe the imaging characteristics of chondrosarcoma so as to improve diagnosis and differential diagnosis accuracy of the disease.Methods:The imaging characteristics of 32 cases of chondrosarcoma confirmed by histopathology were retrospectively analyzed.All the cases had conventional X-ray films,25 cases had CT scanning,14 cases had MRI scanning.Results:Calcification was shown in 28 cases on the conventional X-ray films.Bone invasion and calcification were shown in 25 cases on CT imagings,soft tissue tumor in 21 cases,and periosteal reaction in 2 cases.The tumor was shown as heterogeneous long T1 and long T2 signal on MR imagings,the septa with long T1 and short T2 signal was seen,the calcification with long T1 and short T2 signal was seen too.Septa and the margins of tumor enhancement were seen in the cases with gadolinium-enhanced scaning.Conclusion:The bone invasion,calcification,ring and arc-like septas,and soft tissue tumor were the main imaging characteristics of chondrosarcoma,which had important value in the diagnosis and differential diagnosis of chondrosarcoma.
