【摘要】：目的:探讨孤立性纤维性肿瘤(SFT)的影像表现及病理特征。方法:回顾性分析经病理证实的19例SFT的影像资料,并与病理结果对照分析。结果:(1)19例均为单发,发生于胸膜8例,肾门3例,颅内2例,胸壁、肺、盆腔、颈肩部、腰背部及颌下区各1例,其中1例病理诊断为恶性;病灶最大径3~15 cm;病灶多呈类圆形或不规则形的实性软组织肿块,边界清楚,部分见分叶。(2)CT检查16例,4例密度均匀,12例不均匀,其中5例伴钙化;多期增强扫描多呈"快进慢出"型不均匀强化。MRI检查3例,T_1WI多呈等或稍低信号,T_2WI呈等、低或稍高为主的混杂信号,增强后明显不均匀强化。病灶内部及周围可见肿瘤血管。(3)镜下:肿瘤由疏密不均短梭形细胞、胶原纤维及薄壁血管组成。结论:SFT可发生于全身多部位,影像表现有一定特征,但最终确诊仍需依赖于病理学与免疫组织化学检查。
[Abstract]:Objective: to investigate the imaging features and pathological features of solitary fibrous tumor (SFT). Methods: the imaging data of 19 cases of SFT confirmed by pathology were retrospectively analyzed and compared with the pathological results. There were 3 cases of renal hilum, 2 cases of intracranial, 1 case of chest wall, 1 case of lung, pelvic cavity, 1 case of neck and shoulder, 1 case of waist and back, and 1 case of submaxillary region. The boundary was clear, and partial CT examination showed that 16 cases had homogeneous density and 4 cases had homogeneous density, 5 cases had calcification, and 3 cases showed "fast in and slow out" type of heterogeneous enhancement. MRI examination showed that T _ 1WI was more equal or slightly low signal intensity on T _ 2WI in 3 cases. Low or slightly higher mixed signal intensity, enhanced significantly inhomogeneously. The tumor was seen in and around the lesion under the microscope: the tumor consists of unevenly distributed short fusiform cells, ConclusionSFT may occur in many parts of the body, and the imaging features have certain characteristics, but the final diagnosis still depends on pathology and immunohistochemical examination.
