肺硬化性血管瘤CT影像与病理对照研究

Comparative Study on CT Manifestations and Pathology of Pulmonary Sclerosing Hemangioma

目的分析肺硬化性血管瘤(PSH)的CT表现和病理组织学特点,以提高对该病诊断准确率。资料与方法回顾性分析经手术病理证实9例PSH的CT影像和其病理组织结构特点。结果 PSH多见于中老年女性,肿瘤直径2-5.5cm,呈圆形卵圆形(6例)或浅分叶(3例),边缘清楚,平扫呈较均匀软组织密度,边缘散在点状钙化(4例),增强呈均匀或不均匀明显强化,贴边血管征(5例)、晕征(2例)、局限性肺气肿带包绕征或空气半月征(3例)具有一定特征。肿瘤内结构具有血管瘤样区、乳头样区、实性区、硬化区四种成份。结论掌握PSH的CT影像特点,在肺孤立结节病灶的临床诊断与鉴别诊断应用中具有较大的价值。

Objective To analyza CT findings and histological features of pulmonary sclerosing hemangioma（PSH）,and to improve the diagnostic accuracy of this disease,Mateials and Methods CT images and pathological characteristics of9 cases with PSH confirmed pathologically were analyzed retrospectively.Results PSH mainly showes in middle-agged women,The diameter of lesions was 2-5.5cm.The lesins ere oval or round（6 cases ）or lobulated（3 cases）with peripheral scattered stiopled calcificatin（4 cases）,shoeed homogeneous of heterogeneous enchancement,The characteridstioc finding such as bypaa vascular sign（5 cases）,halo sign（2 cases）,local emphusema area surrounded the mass or air meniscus sign（3 cases ）were found ,The neoplasms have four histological companents in fifferent regions hemorrhagic region ,papollary region ,solod region, and sclerotic region Conclusion There is great applocation value in clinical diagnosis and differential diagnosis of insolotary pulmonary nodule to familiar with CT imaging features of PSH.
