| 摘 要： | 目的 探讨隆凸性皮肤纤维肉瘤(DFSP)的MRI表现。方法 收集经病理证实的8例DFSP患者,回顾性分析其MRI表现。结果 8例DFSP中,病灶位于躯干3例,四肢5例,均位于皮肤及皮肤下层,肿瘤最大径1.8~11.6 cm。T1WI示8例肿瘤呈等或略低于肌肉信号,T2WI示肿瘤呈明亮高信号,2例病灶内部见斑点状低信号;脂肪抑制(STIR)序列示6例肿瘤呈高信号;1例对比剂动力学时间分辨成像(TRICKS)动态增强MRA示肿瘤的供血血管为腓动脉。6例接受增强扫描者病灶均明显强化,2例病灶内见斑点状无强化出血区。结论 DFSP好发于四肢、躯干及头颈部皮肤及皮下组织,其MRI表现具有一定特征性。
