摘　　要：目的:探讨肺隔离症(PS)的CT表现及特点。方法:回顾分析12例经临床病理证实的PS的CT表现,观察其位置、大小、形态、内部结构、边缘征象、外周改变及增强表现,总结其CT影像特征。结果:12例PS中,男8例,女4例,年龄最大62岁,最小2岁;平均20.21岁。10例位于左肺下叶,2例位于右肺下叶,9例叶内型,3例叶外型。影像表现6例异常的肺实质内含有充液或不充液的囊腔,3例可见囊或结节环绕的低密度区,2例见多发扩张的血管,1例示软组织密度肿块。12例对比剂增强螺旋CT扫描10例显示了病变的异常血管。结论:PS多具肺内感染性病变影像表现。对比剂增强螺旋CT扫描是PS诊断及鉴别诊断的重要手段。Objective：To discuss the CT imaging manifestations of pulmonary sequestration and its characters. Method：The CT imaging manifestations of 12 clinical pathologyproved pulmonary sequestrations were retrospective analyzed. The size, configuration, inter structure, margin and feature of enhancement were summarized and analyzed. Result：There were 8 males and 4 female in 12 cases of PS,The age ranged from 2 to 62 years （mean20. 21years）. 10 cases were located in inferior lobar of left pulmonary, 2 cases were located in inferior lobar of right pulmonary. The imaging manifestations showed that 6 cases had cyst with liquid or without liquid in abnormal pulmonary parenchyma, 3 cases can be seen cyst or low density area with nodules,2 cases can be seen muhitude of muhifocal dilatants vascular, 1 case was shown with soft tissue mass. 10 of 12 cases have abnormal arterial supply scanned with contrast-enhanced spiral CT. Conclusion：Most PS have imaging characters of infectious, Contrastenhanced spiral CT is an important means for diagnosis and differential diagnosis the pulmonary sequestration.
