目的：探讨纤维肉瘤的影像学表现，提高对该病的诊断水平。方法：回顾性分析本院2011年1月－2013年12月经手术病理证实的14例成人型纤维肉瘤患者的病例资料，其中隆突性皮肤纤维肉瘤5例。14例均行 MRI平扫，其中6例加做增强扫描。结果：5例隆突性皮肤纤维肉瘤均发生在表浅软组织内或隆起于皮肤表面，另外9例纤维肉瘤中6例累及深部肌肉，2例同时累及深部肌肉与表浅软组织，7例病灶与周围深筋膜关系密切。14例纤维肉瘤 MRI 表现为T1 WI等高信号，T2 WI混杂信号，10例病灶内见条状低信号分隔，5例见囊变坏死，1例病灶内可见出血，4例伴周围软组织水肿，4例伴发骨转移。6例增强扫描病灶呈外周强化或＂轮辐状＂强化。结论：MRI能清楚显示病灶的位置、大小、形态及组织结构特点，有助于提高纤维肉瘤的影像学诊断与鉴别诊断水平。

Objective:To investigate the imaging features of fibrosarcoma,in order to improve the diagnostic level of fibrosarcoma.Methods:The data of 14 patients with adult fibrosarcoma confirmed by histopathology were retrospectively analysed in our hospital from January 2011 to December 2013.Five of the 14 cases were dermatofibrosarcoma protuberans. All subjects underwent MRI examination and 6 of them underwent contrast enhanced MRI.Results:5 cases of dermatofibro-sarcoma protuberans located in the superficial soft tissues.Of the other 9 cases of adult fibrosarcoma,6 cases involved the deep muscle,2 cases involved both of the deep muscle and the superficial muscle,7 cases were closely related with the pe-ripheric deep fascia.All of the lesions showed hyperintensity to isointensity on T1 WI and heterogeneous signal on T2 WI.10 cases showed hypointensity of the septa within lesions.5 cases showed cystic or necrosis area.One case showed bleeding within the lesion.4 cases showed edema in the peripheral soft tissue,4 cases involved the adjacent bone.6 cases showed pe-ripheral or spoke-like enhancement on contrast MRI.Conclusion:MRI is an accurate method in describing the location,size, shape and character of fibrosarcoma.and is helpful for diagnosis and differential diagnosis of fibrosarcoma.
