Abstract Objective: To investigate the imaging manifestations and pathological features of solitary fibrous tumors. Methods: The imaging data of 19 cases with solitary fibrous tumor confirmed by pathology were retrospectively analyzed and compared with the corresponding pathological results. Results: ①All of the 19 cases had single lesion, 8 cases occurred in the pleura, 3 in the renal hilum, 2 in the central nervous system, and the wall of the chest, lung, pelvic cavity, neck and shoulders, the back of the lumbar and the submandibular region each had 1 case occurred; One case among them was malignant. The tumors ranged from 3~15 cm in maximum diameter. The tumors were mostly quasi-circular or oval or irregular solid soft tissue masses with clear boundary, some of them were lobulated. ②In the 16 cases of CT examination, 4 lesions showed homogeneous density, 12 lesions showed heterogeneous density, 5 cases of which had calcification; Most of the lesions showed uneven enhancement; The multiphase scanning type is “fast in and slow out”. Three patients underwent MRI. Most of the lesions showed equal or slightly low signal on T1WI, mixed signal on T2WI. The lesions were obviously enhanced on enhanced T1WI. Histologically, the tumor were formed with hyper-and hypo-cellular spindle cells, dense collagenous fibers and thin-walled blood vessels. Conclusion: SFT can occur in many parts of the body and the imaging manifestations have certain characteristics. The final diagnosis still needs pathological and immunohistochemical examination.
