肺硬化性血管瘤的CT诊断价值

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。

Diagnostic value of CT for pulmonary sclerosing hemangioma

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.
