目的探讨胸部孤立性纤维性肿瘤的CT表现及病理特征。方法回顾性分析16例经病理证实胸部孤立性纤维性肿瘤影像资料，并与病理形态进行对照研究。所有病例均行CT平扫及增强扫描。结果在16例病例中，14例病灶表现为实性病灶，边界光滑；2例呈囊实性改变，且呈分叶状。增强扫描病灶实性部分轻度强化，延迟扫描实性部分进一步呈"地图样"强化。良性SFT病理表现为梭形细胞与胶原纤维以不同比例分布，分别构成细胞疏松区与细胞密集区；恶性SFT则表现为细胞异型性明显，病理核分裂像增多。免疫组化结果显示，Vimentin及CD34阳性。结论胸部孤立性纤维性肿瘤具有较为特异的影像表现，形态学的检查有助于此病的诊断及定性。

Objrctive We aimed to analyze the computed tomography (CT) and pathological features findings of solitary fibrous tumors (SFT). Methords CT and pathology images of 16 patients with SFT confirmed by pathology were retrospecively reviewed, and a comparison with immunohistochemical and histopathological results were made. Results 14 cases showed solitary rouned wel -defined masses, and 2 cases showed cystic solid masses.Contrast-enhanced images showed marked, heterogeneous enhancement, and delayed enhancement.The pathological features of SFT contained mixed various amount of spindle cells and collagen, with CD34 and Vimentin being immunohistochemical positive. The malignate cases demonstrated cytological atypia obviously and tumor necrosis.Conclusion SFT and can demonstrated characteristic CT features, which is helpful for the diagnosis, yet final diagnosis should be based on pathology examinations.
