目的：探讨CT、MRI对隆突性皮肤纤维肉瘤（ DFSP）的诊断价值。方法16例经病理证实为DFSP的患者，对其CT以及MRI图像进行分析，总结DFSP的影像特点。16例中，女10例、男6例，肿块超过1年的15例、超过5年的11例，有复发病史的9例。结果肿块在CT上密度较实，增强扫描强化不均匀；T1 WI信号稍低，T2 WI信号稍高，信号不均匀，增强扫描强化不均匀。肿块直径＜5 cm的3例、直径＞5 cm的13例，肿块与邻近肌肉分界清楚的15例、外形有“悬吊征”7例、边缘部有“子结节外突征”10例，肿块内有“多结节征”12例，肿块基底部向周围脂肪层内形成“树根状”生长征象的8例。结论 DFSP在CT和MRI上有其表现特点，依据这些特点可以对其做出较准确的诊断。

Objective To explore the diagnostic significance of CT and MRI in dermatofibrosarcoma protuberans.Methods Analyze the CT and MRI images of 16 cases which were confirmed as dermatofibrosarcoma protuberans by pathology.The medical imaging features of dermatofibrosarcoma protuberans were summarized.In the total 16 cases(including 6 male cases,10 female cases),15 cases had suffered from dermatofibrosarcoma protuberans for more than 1 year, 11 cases for more than 5 years, and 9 cases had history of recurrence.Results On MRI, the mass was slightly hypointense on T 1 WI, inhomogeneously hyperintense on T 2 WI with inhomogenous enhancement.The diameters of mass were less than 5 cm in 3 cases,and were more than 5cm in 13 cases.Fifteen cases had clear demarcation between the masses and their adjacent muscles , 7 cases had “suspension sign” in shapes, 10 cases had “sub-nodules outward” features at the edge of the tumors , 12 cases had “multinodular” features inside the tumor , and 8 tumors grew into the surrounding fat layer like roots.Conclusion Dermatofibrosarcoma protuberans can be diagnosed accurately based on the features displayed on CT and MRI.
