摘　　要：目的探讨肺硬化性血管瘤(PSH)的影像学特点,提高其术前诊断的准确性。方法搜集11例经手术病理证实的PSH,将其影像学表现与手术病理结果进行回顾性对照分析。结果PSH影像表现多是肺孤立性肿块,密度不均匀,病变轮廓清楚,边缘光滑者10例,边缘不规则者1例;1例可见小的钙化,1例见空气新月征。CT增强扫描病灶明显强化,7例均匀强化,4例强化不均匀。CT与病理的关系是病变的高密度与低密度区分别对应于其血管瘤成分与囊变区。结论PSH的胸部平片和CT平扫无明确特征表现,增强扫描对病变的诊断和鉴别诊断起着关键作用。Objective To analyze the imaging characteristics of pulmonary sclerosing hemangioma （PSH） and to improve the accurate rate of its diagnosis before surgery. Methods Imaging findings in 11 cases pathologically proved sclerosing hemangiomas were retrospectively analyzed in comparison with pathology. Results The imaging findings of PSH mostly were solitary masses with homogeneous density, and with smooth margin in 10 cases and irregular margin in 1 case;1 case with slight calcification and 1 case with air - meniscus sign were found. 7 cases were homogeneous enhancement and 4 were heterogeneous enhancement on contrast - enhanced scan. The high and low attenuation areas on CT corresponded with angiomatous and cystic areas respecitvely on pathology. Conclusion Chest roentgenogram and unenhanced CT scan of PSH are not of remarkable characteristics,contrast - enhanced CT scan plays an important role in diagnosis and differential diagnosis of PSH.
