摘　　要：目的探讨硬化性肺泡细胞瘤(PSP)的CT特征.以提高临床诊断水平。方法回顾性分析经手术病理证实的16例PSP的临床及CT资料。结果本组16例中男2例,女14例,50岁以上女性12例。16例均为单发类圆形结节或肿块影。12例位于右肺,4例位于左肺。10例密度均匀;4例可见钙化,其中1例弥漫钙化;2例出现囊变。12例行增强扫描,均呈渐进性明显强化,5例出现贴边血管征,1例出现空气新月征,1例出现晕征。结论肺内孤立性结节或肿块岀现钙化和/或“血管贴边征”、“空气新月征”、“晕征”等,高度提示PSP可能性。Objective To investigate the CT features of pulmonary sclerosing pneumocytoma ( PSP) so as to improve the level of clinical diagnosis. Methtxls Clinical and CT features of 16 patie nts with PSP con firmed by surgery and pathology were an alyzed retrospectively. Kesults Of 16 patients,2 were male and 14 were female,including 12 female patients over 50 years old.All 16 lesions were solitary round nodules or masses. 12 lesions were located in the right lung and 4 in the left lung.There were 10 lesions with uniform density, and 4 lesions with calcification, in which 1 case was diffused calcification ,and 2 lesions had cystic degeneration.The enhanced scan was performed in 12 patients and all lesions were obviously enhanced.5 lesions appeared welt vessel sign, 1 lesion showed the air crescent sign, and 1 lesion presented halo sign .Conclusion If a solitary pulmonary nodule or mass in the lung shows calcification with (or)"vascular border sign**,"air crescent sign","dizzy sign" and other CT manifestations, the possibility of PSP will be considered.
