Abstract：Objective: To investigate the CT findings of thoracic solitary fibrous tumors(SFT). Methods: CT images of 25 patients with thoracic SFT confirmed by surgery and pathology were retrospectively analyzed. Results: All cases had single lesion. Twenty-three lesions originated from the pleura, 2 lesions from the lung. The mean diameter of the 25 lesions is 10.9 cm on CT images. All lesions presented as round or oval with well-defined margins, in which 10 cases(10/25) were lobulated, 4 cases(4/25) had calcification. On plain CT, heterogeneous density was showed in 6 cases(6/9), and homogenous isodensity was showed in 3 cases(3/9). On contrast enhanced CT, unevenly moderate or intensive enhancement presented as “geographic pattern” was demonstrated in 15 cases(15/21). Disorganized vessels with obvious enhancement were showed in 14 masses during arterial phase. Multiple nodular enhancement was seen in 8 masses, pathy and cystic non-enhancement areas were seen in 13 cases. There are significant differences in some CT findings between different size of SFT(P＜0.05). Conclusion: Thoracic SFT usually presents as single, huge mass with well-defined margins and contains various components. Multiple nodular enhancement and inner vessels in disorder are the characteristics of thoracic SFT on contrast-enhanced CT images.
