Abstract:
Objective To study the CT appearances of solitary fibrous tumors of pleura,in order to improve the knowledge of this diseases.Methods CT findings of solitary fibrous tumors of the pleura proved by pathology in 6 cases were retrospectively analysed with literatures review.Results 6 cases of solitary fibrous tumors of the pleura were all seen in the right thoracic cavity.The tumor was about 3 cm in maximum diameter in one case,and the other 5 cases,the tumors were over 9 cm in maximum diameter.On plain CT scans,all tumors were smooth at edge and with wide base connected to the pleura,the density of tumors were homogeneous in 4 cases,the CT values were 28~39 HU,in the other 2 cases,the tumors were unhomogeneous slightly with low density inside the tumors,CT value of the tumors were 12~40 HU.On contrast-enhanced CT scans in 4 cases,3 tumors showed moderated enhancement and distort vessels could be seen,the CT value were 44~52 HU,the lesions enhanced increasing 12 HU,1 case was obviously unhomogeneous enhancement,the lesions enhanced increasing 22~50 HU and "Pseudo-capsules" were demonstrated in 3 cases.Conclusion Solitary fibrous tumors of the pleura has certain CT characteristics.
