摘　　要：目的:探讨肺硬化性血管瘤的CT表现特征,以提高其CT诊断准确性及鉴别诊断的能力。方法:回顾性分析18例经手术和病理证实的肺硬化性血管瘤的CT表现,其中11例行CT增强扫描。结果:术前诊断有一定的难度。中年女性为主要发病群体。女性17例(17/18,占94.44%),43～70岁之间共15例(15/18,占83.33%)。发病部位集中于左下肺(9/18,占50.00%)。18例肺内类圆形肿块边界清楚,6例见斑点状钙化(6/18,33.33%),3例见浅分叶,1例有纵隔淋巴结肿大,所有病例均无空洞,无胸膜凹陷和受侵,无血管切迹征。CT值为26～40Hu。11例增强CT中10例(10/11,占90.91%)病灶呈明显强化,有一定的延迟强化,CT值增加46～60Hu以上。结论:CT对于肺硬化性血管瘤的准确诊断具有一定的价值,增强CT是必要的补充手段。objective： To study the CT feature of pulmonary sclerosing hemangioma （PSH）, and improve the diagnosi＇s accuracy and differential diagnosis of PSH by CT scanning. Methods： The CT images of 18 PSHs confirmed operation and pathology were retrospectively analyzed, and 11 cases followed enhanced CT scanning. Result： It is very difficulty in preoperative diagnosis and main group of PSH is middle-aged women. Of those 18 cases, female were found in 17 cases （17/18, 94.44%）, and patients aged in 43-70 years were found in 15 cases （15/18, 83.33%） and whose tumors were located in the left lower lung zone accounted for 50.00%. The tumors were round with clear edge （18/18, 100/%）, were slightly lobulated （3/18）, had punctate calcification （6/18, 33.33%）, and had mediastinal lymph node （1/18）. All cases were without cavity, pleural sag and metastasis, and vascular incisura. The CT values of observed cases were between 26-40 Hu. Among 11 cases followed enhanced CT scanning, 10 cases showed obvious enhancement and delay enhancement to a degree, and the CT values were increased over 46-60 Hu. Conclusion： The CT scanning is helpful for the diagnosis of PSH. Enhanced CT could be helpful to diagnosis,
