摘　　要：目的:探讨肺硬化性血管瘤(PSH)的MSCT表现,提高临床诊断水平。方法:回顾性分析14例肺硬化性血管瘤的临床、病理及MSCT表现。结果:14例PSH均为单发,病灶位于右肺5例,左肺9例;肺叶分布为上肺3例,中肺1例,下肺10例。MSCT平扫肿瘤均呈圆形或类圆形软组织结节或肿块;5例可见轻分叶,10例密度均匀,2例瘤内可见不规则钙化。增强扫描病灶大多呈中度至明显不均匀强化;14例中不均匀强化8例,均匀强化6例;中度及明显强化12例,轻度强化2例;MSCT表现与病灶由血管瘤样区、乳头区、实变区和硬化区以不同比例构成相关。结论:肺硬化性血管瘤MSCT常表现为良性肿瘤特征,图像后处理有利于病变细微结构的显示,综合分析MSCT征象有利于提高其诊断符合率。Objective：To study the MSCT manifestations of pulmonary sclerosing hemangioma（PSH）,in order to improve the capability of accurate diagnosis.Methods：The clinical,MSCT and pathological features in 14 cases of PSH were analyzed retrospectively.Results：All the tumors of the 14 cases were single,with 5located in the right lung and 9in the left.In terms of their distribution in pulmonary lobes,3were found in the upper lobe,1in the middle lobe and 10 in the lower lobe.Under unenhanced MSCT,tumor presented as round or oval shaped nodule or mass with soft tissue density.5cases showed slight lobulation.10 tumors were even in density,with only 2cases had intra-tumoral small amount of irregular calcifications.After contrast administration,most of the tumors showed moderate-marked inhomogeneous enhancement.Of the14 cases,heterogeneous enhancement was assessed in 8cases and homogeneous enhancement in 6cases,12 cases showed moderate-marked enhancement,mild enhancement in 2cases.These MSCT manifestations were due to different tissue components within the tumor,including hemangiomatous area,papillary area,solid area and sclerotic area with various proportion.Conclusion：The MSCT appearances of PSH usually displayed as pulmonary benign tumor,post-processing technique is helpful in demonstrating the details of lesion.Therefore,a comprehensive analysis of all the MSCT features can help to improve the accuracy of diagnoses.
