【摘要】：目的探討孤立性纖維性腫瘤(SFT)的CT與MRI特征。方法回顧性分析經(jīng)手術(shù)病理證實(shí)的10例SFT的CT與MRI資料,將CT與MRI表現(xiàn)與手術(shù)病理結(jié)果對照觀察。結(jié)果 (1)10例SFT中,3例位于胸部,1例位于顱內(nèi),4例位于腹盆腔,2例位于體表軟組織;其中3例病理學(xué)診斷為惡性。腫瘤最大徑1.5~21.8 cm。瘤體大多為實(shí)性,邊緣清楚,多呈不規(guī)則形,少數(shù)邊緣分葉狀。(2)6例行CT掃描,瘤體密度均勻/混雜,部分伴有點(diǎn)狀鈣化及小片狀出血;增強(qiáng)掃描呈明顯均勻或不均勻"快進(jìn)慢出"型強(qiáng)化,腫瘤血管多見。(3)4例行MRI掃描,T1WI上多呈不均勻等低信號(hào),T2WI上呈以高信號(hào)為主的混雜信號(hào),增強(qiáng)掃描呈明顯不均勻強(qiáng)化;1例呈現(xiàn)多房囊樣腫瘤的信號(hào)特點(diǎn)。(4)顯微鏡下腫瘤由疏密不均的梭形細(xì)胞、致密膠原間質(zhì)以及大量薄壁血管組成。結(jié)論 SFT是一種可發(fā)生于全身各部位的梭形細(xì)胞腫瘤,確診仍依靠病理學(xué)及免疫組織化學(xué)檢查,影像學(xué)檢查尤其CT掃描具有一定特征性。
[Abstract]:Objective to investigate the CT and MRI features of solitary fibrous tumor (SFT). Methods CT and MRI findings of 10 cases of SFT proved by operation and pathology were analyzed retrospectively. The findings of CT and MRI were compared with the results of operation and pathology. Results of the 10 cases of SFT, 3 cases were located in the chest, 1 case was located in the skull, 4 cases were located in the abdominal and pelvic cavity, 2 cases were located in the soft tissue of the body surface, and 3 cases were diagnosed as malignant by pathology. The maximum diameter of the tumor was 1.5 ~ 21.8 cm 路cm ~ (-1). Most of the tumors were solid, with clear margin and irregular shape. A few of them were divided into lobes. 6 cases were scanned by CT. The density of the tumor was even / mixed, and some of them were accompanied by calcification and small hemorrhage. Contrast-enhanced scan showed obvious homogeneous or uneven "fast in and slow out" enhancement, and most of the 4 cases of MRI scan showed heterogeneous and homogeneous low signal intensity on T _ 1WI, which were mainly mixed signal on T _ 2WI. One case presented signal characteristics of multilocular cystic tumor. Under the microscope, the tumor was composed of dense and uneven spindle cells, dense collagen stroma and a large number of parenchyma vessels. Conclusion SFT is a spindle cell tumor that can occur in all parts of the body. The diagnosis of SFT still depends on pathological and immunohistochemical examination.
