Abstract:
Objective To investigate the CT manifestations and pathology features of solitary fibrous tumors of the pleural (SFTP),to improve diagnostic accuracy of this disease.Methods CT manifestations of 12 cases with SFTP confirmed by surgery were analyzed retrospectively by comparison with the pathological findings.Results The CT images of the 12 cases showed intrathoracic soft-tissue shadow with well-defined margin which was widely connected with pleural.There were 4 cases with mound like and mushroom shape,3 cases with round or oval shape,2 cases with irregular shape growing into the pleural space,3 cases with large mass filling unilateral thoracic cavity,9 cases with pleural tail sign and 1 case with pleural pedicle sign.The plain CT showed homogeneous density in 7 cases,high-low mixed density in 4 cases and with internal calcification in 1 case.After contrast enhancement,5 cases were map like heterogeneous and progressive enhancement,and 4 cases have strip distorted vessel inside or on the edge of the lesion.Conclusion CT manifestations of SFTP have certain characteristics,such as broad base,shaping growth and pleural tail sign,which could be helpful to improve the diagnostic accuracy of SFTP by analyzing carefully.
