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。 Objective: To investigate the imaging features and clinical value of keratosis type fibrosarcoma. Methods: 11 cases of keratoconjunctival cutaneous fibrosarcoma were collected to analyze the clinical and imaging features. Results: MRI showed regular or irregular lumps in subcutaneous fat, most of them were round or round, with clear boundary. T1WI showed low signal, which was similar to muscle signal, T2WI showed slightly higher signal and Gd-DTPA increased Scanning, was significantly uniform enhancement; CT showed a slightly lower density, slightly lower than the muscle density, the boundaries are relatively clear, enhanced enhanced scan significantly. CONCLUSION: The imaging findings of keratosis type fibrosarcoma have certain characteristics and have certain clinical value. Correct diagnosis can be made according to clinical and imaging features.
