肺硬化性血管瘤的CT影像表现

CT demenstration of pulmonary sclerosing hemangioma

目的分析肺硬化性血管瘤的CT表现,提高诊断准确率。方法回顾性分析12例手术病理证实的肺硬化性血管瘤的CT表现的特点。结果肺硬化性血管瘤呈类圆形或卵圆形结节灶、肿块,边缘光整,境界清,位于左肺者略多,钙化2例,1例同时有空气新月征及晕征,增强病灶多呈明显强化,2例可见贴边血管征。结论中年妇女肺部孤立性结节或肿块,边缘光整、境界清,明显强化,伴有空气新月征者,需重点考虑肺硬化性血管瘤。

Objective To study the CT demenstration of pulmonary sclerosing hemangioma（PSH） and improve the accuracy of diagnosis.Methods 12 cases with pulmonary sclerosing hemangioma confirmed pathologically were retrospectively analyzed.Results PSH was round nodule or mass with clear margin and was located in the left lung.2 cases had calcification and 1 case showed both air meniscus sign and ground-glass opacities.Most lesions were obviously enhanced and vascular notch symptom was observed in 2 cases.Conclusion When an isolated pulmonary nodular or mass is observed in a middle-aged woman with obviously enhanced clear margin and air meniscus sign,pulmonary sclerosing hemangioma should be preferentially considered.
