Abstract:
Objective To discuss the imaging features of the localized fibrous tumor of pleura(LFTP).Methods 10 cases of LFTPproved patholgically were underwent CT scanning,while MRI scanning was performed in 3 cases.The imaging findings of LFTP wereanalysed.Results 9 cases were benign tumors and 1 case was malignant tumor.The main CT manifestations were single soft tissue massadhering to the pleural surface,clearly boundary,homogeneous or unhomogeneous density,obvious homogeneous or non-uniformityenhancement."Pleura mass hat"was characteristic appearance located the pleura mass.The mass formed acute angle or obtuse angle with the adjacent pleura,which was related to mass size and shape.MRI manifestations were hypointense or isointense on T_1WI and T_2WI,non-uniformity signal.1 case of giant LFTP showed scattered in disorder and clutter signal on T_2WI.Inside tumor peduncle of the giant LFTP was connected with the pericardium.Conclusion CT is a main imaging diagnostic technique for LFTP,while MRI is commonly superior to CT in localizing the mass and showing inner characteristics for the bigger pleural masses.The appearance of pleuraL tumor peduncle is an important sign in diagnosis of LFTP.
