Objective The aim of the study was to analyze the CT morphology features of pulmonary sclerosing hemangiomas (PSHs) and improve the diagnosis ability of this disease. Methods The 18 cases of pulmonary sclerosing hemangioma (PSH) confirmed by operation and histopathology from August 2002 to May 2009 were collected, including 17 females and 2 males, aged from 19 to 60 years old, with an average age of 43 years. All the cases underwent plain CT scan, among them, 16 cases received enhanced CT scan. Results The 18 cases had isolated mass. Mean long-axis diameter of these lesions was (2.7 ± 1.3) cm (range, 1.9-.2 cm). Of all cases, 5 cases (27.8%) were round in shape, 9 cases (50%) were oval, 4 cases (22.2%) were lobulated, and 14 cases (77.8%) were smooth margin. The air meniscus sign was in 2 cases (11.1%), and the halo sign in 3 cases (16.7%). Two cases (11.1%) contained small nodular calcification, the remaining 16 cases (70%) were homogeneous density, the CT density of the masses ranged from 24-7 HU, and the mean value was 35 HU. Sixteen cases received enhanced scan, the welt vessel sign was in 8 cases (44.4%),1 case showed less enhancement, 5 cases showed marked homogeneous enhancement and 10 cases showed intense and patchy heterogeneous enhanced. The CT density of the enhancing masses ranged from 60-10 HU, the mean value was 35 HU, and the net enhancement value was 14-0 HU, the mean value was 55 HU. Conclusion PSH should be considered in middle-aged female whose CT found that single round or oval pulmonary nodules, with smooth margin, or associated with the air meniscus sign, the halo sign, or the marked enhancement.
