摘　　要：目的:探讨CT对肺硬化性血管瘤(PSH)的诊断价值。方法:回顾性分析12例经手术病理证实的PSH的CT表现,4例行CT平扫和增强扫描,8例仅行CT平扫。结果:12例病灶呈圆形或类圆形,8例密度均匀(8/12,66.7%),边缘光滑,其中2例出现轻度分叶(2/12,16.7%);4例密度欠均匀(4/12,33.3%),边缘可见点状钙化,其中2例可见"空气新月征"(2/12,16.7%)。12例平扫平均密度值约50HU,4例增强扫描均显著强化,密度值达90～110HU。结论:CT在一定程度上有助于PSH的诊断,但该病确诊仍依赖病理学检查。Objective：To study the diagnostic value of CT for pulmonary sclerosing hemangioma（PSH）.Methods：CT features of 12 cases with PSH proved by operation and histopathology were analyzed.4 cases underwent CT plain scan and enhanced scan.The other 8 cases just underwent CT plain scan.Results：All of the 12 cases were round in shape.8 lesions of the 12 cases showed a uniform density（8/12,66.7%）,with regular edge,two of which had slight lobulated shape（2/12,16.7%）;4 cases showed punctate calcification（4/12,33.3%）,two of which presented with ＂air meniscus sign＂（2/12,16.7%）.The average density value of lesions on percontrast CT was 50HU.After contrast administration,4 cases showed prominent homogeneous enhancement,and the density value reached to 90~110HU.Conclusion：CT can be helpful in the detection of pulmonary sclerosing hemangioma,however,definite diagnosis depends on pathology.
