Objective To explore the diagnostic value of MSCT in solitary fibrous tumor of the pleura(SFTP).Methods The clinical and CT data of 12 patients with SFTP confirmed by pathology were analyzed retrospectively.Results The main clinical symptom and CT findings of 12 patients with SFTP included:chest tightness(n=8),dyspnea(n=6),chest pain(n=5),cough(n=2);round (n=7),irregular(n=5);envelope(n= 6),lobulation(n= 5 );necrosis (n= 9),calcification (n= 3);the diameter was 3 - 22 cm, mean (11.3±2.4)cm;clear boundaries between lesions and lung tissue(n=9),an acute angle between lesions and chest wall(n=7);uneven obviously “map-like”enhancement after injecting contrast medium,which 7 cases of lesions can be seen in the circuitous vasculature and 3 cases was showed mild-moderate enhancement.Conclusion SFTPs have characteristic CT features,contrast enhanced CT play an unique advantage.
