摘　　要： 目的:探讨成人型纤维肉瘤的MRI表现。方法:收集经手术病理证实的13例成人型纤维肉瘤患者的MRI资料,将其MRI平扫及增强扫描基本特征进行回顾性影像分析,探讨MRI征象在诊断与鉴别诊断中的价值。结果:肿瘤位于四肢9例,肩背部、腹膜后、腹腔、颈部各1例。MRI平扫病灶主体T1WI呈低、等信号,T2WI呈脑回状混杂信号;7例伴周围软组织水肿,3例见囊变、坏死,1例侵犯邻近骨质。增强扫描12例呈明显边缘性或"轮辐"状强化,1例呈不均匀强化。结论:成人型纤维肉瘤在MRI表现上有一定的特征性,MRI对病变的诊断及鉴别诊断具有重要的价值。 Objective To analyze the MRI imaging manifestations of adult fibrosarcoma. Methods Thirteen patients with pathologically proved adult fibrosarcoma were selected. The clinical data and MRI features of all patients evaluated retrospectively. Results Nine cases located in limbs. The other four cases located in neck, shoulder and back, abdominal or retroperitoneal cavity, respectively. All the lesions showed hypointense to isointense signal on T1-weighted imaging and heterogeneous gyri—like signal on T2-weighted imaging. 7 cases showed edema signal in surrounding muscles. 3 eases showed cystic or necrotic area. 1 case involved the adjacent bone. On gadolinium contrasted MRI, 12 cases showed peripheral or spoke-like enhancement. The other one showed unevenly enhancement. Conclusion The MRI manifestations of adult fibrosarcoma have certain characteristics. MRI plays an important role in diagnosis and differential diagnosis of adult fibrosarcoma.
