Abstract：Objective To investigate the CT features of pulmonary sclerosing hemangioma ( PSH) so as to improve the accura-cy of diagnosis of this condition .Methods Clinical, pathological and CT data of 19 cases of pulmonary sclerosing hemangioma diagnosed pathologically were collected .Results 22 PSH lesions of 19 cases were proved, including 16 females and 3 males.Of 19 cases, 1 case was central type and 18 cases showed peripheral types including 1 hilar lesion and 17 cases around hilum of lung.1 case appeared multiple ground-glass-like density and 18 cases showed soft tissue density .18 cases showed regular edge and 7 cases had slight lobulated sign , 4 cases showed uneven density and 8 cases appeared heterogeneous enhancement , in which marked enhancement was seen in 10 cases and moderate enhancement was seen in 6 cases, and 3 cases showed mild enhance-ment.Blood vessel marginating signs were observed in 10 cases and halo signs were seen in 4 cases.1 case presented air menis-cus sign and 5 cases showed punctuate calcification .4 were located in right upper lobe , 2 located in right middle lobe and 5 loca-ted in right lower lobe .1 was located in left upper lobe , 3 located in left lower lobe and 2 cases located in translobes .2 cases showed multiple lesions , and 2 cases were accompanied mediastinal lymphadenectasis .Conclusion The CT features of pulmona-ry sclerosing hemangioma have certain characteristics .Based on patients’ age, gender, pathological features, the misdiagnosis will be reduced .
