摘    要:目的:探讨隆突型皮肤纤维肉瘤的影像学特点及临床价值。方法:收集11例隆突型皮肤纤维肉瘤分析其临床及影像学特点。结果:MRI表现为皮下脂肪内规则或不规则肿块,大部分呈圆形或类圆形,边界清楚,T1WI呈低信号,与肌肉信号相当,T2WI呈较均匀稍高信号,注射Gd-DTPA增强扫描,呈明显均匀强化;CT表现稍低密度,较肌肉密度稍低,界限相对清楚,增强扫描明显强化。结论:隆突型皮肤纤维肉瘤的影像学表现具有一定特征性并具有一定临床价值,结合临床及影像特点可做出正确诊断。

Abstract:Objective To investigate the clinical value and imaging features of dermatofibrosarcoma protuberans.Methods The clinical and imaging characteristics of 11 cases with dermatofibrosarcoma protuberans were investigated and analyzed. Results Magnetic resonance imaging(MRI) data showed that most of regular or irregular lumps in subcutaneous fat were round or oval with clear boundary, and the T1WI showed that low signal, which was similar as muscular, while the T2WI showed slightly stronger signal with the injection of Gd- DTPA. CT data showed slightly low density, which was lower than the muscle density. The boundary was relatively clear, and obvious enhancement was observed. Conclusion The imaging features of dermatofibrosarcoma protuberans show a certain characteristic and clinical value, which can make the correct diagnosis by combining with the clinical characteristics.
Keywords:Dermatofibrosarcoma protuberans  Magnetic resonance imaging  Computed tomography
