摘　　要：目的 :探讨肺硬化性血管瘤 (SHL)的影像学表现 ,评价其诊断价值。方法 :回顾性分析 9例经手术证实的SHL影像与临床资料 ,女 8例 ,男 1例 ,年龄 40～ 71岁 ,平均 57.1岁。结果 :影像表现为 :①平片 :表现为境界清楚的孤立结节或肿块 ,无毛刺、钙化及胸膜凹陷征 ,密度均匀 ;②CT :胸膜下、肺实质内孤立肿块、边缘光整、密度均匀、偶见钙化 ,增强表现为明显均匀或混杂强化 ;③MRI:T1 WI信号高于肌肉 ,T2 WI为高信号 ,T1 WI和T2 WI均夹杂部分点状低信号 ;动态增强其强化峰值出现于 2 .5min ,静态增强为均匀、中等强化。结论 :SHL的诊断主要依靠CT平扫及增强扫描 ,MRI尤其是动态与静态增强扫描有助于鉴别诊断。Objective:To study imaging findings of sclerosing hemangiomas of the lung (SHL) and assess their diagnostic value.Methods:Nine cases of SHL proved by surgery and pathology were analyzed retrospectively.There were eight female and one male,ranged in age from 40 to 71 years with average of 57.1 years.Results:The plane film findings of SHL were well defined and homogeneous dense isolated nodule or mass without speculation,calcification and pleural indentation. On CT,SHL appeared as heterogeneous density and well defined juxtapleural isolated masses in pulmonary parenchyma.Calcification was seen occasionally.Masses were enhanced homogeneously or heterogeneously.On MRI, two nodules showed slightly higher signal intensity than muscle on T 1WI and heterogeneous signal intensity on T 2WI.The lesion was homogeneously and moderately enhanced and the mean peak of dynamic enhancement appeared at 2.5min after intravenous administration of Gd DTPA. Conclusion:The diagnosis of SHL depends on CT,especially with thin section and enhanced contrast scanning.MRI,particularly with dynamic and static enhanced scanning,can be helpful for differential diagnosis.
