摘　　要：目的研究儿童肺隔离症的CT表现。方法回顾性分析2000-2008年经手术及病理证实的肺隔离症患儿15例，全部病例均行CT平扫，10例对病灶薄层增强扫描，其中肺叶内型11例，肺叶外型4例。结果15例均位于肺下叶后基底段，囊性8例，实质性4例，囊实性3例，CT增强扫描发现来自体循环异常供血动脉。结论肺隔离症主要表现为肺下叶后基底段的囊性、实性或囊实性的软组织阴影。Objective To study CT appearances of congenital pulmonary sequestration in children. Methods 15 children with pulmonary sequestration from 2000 to 2008 confirmed by surgery and pathology were retrospectively analysed. All cases were examined with plain CT scans and 10 of them underwent thin slice contrast-enhanced CT scan. There were intra-pulmonary type in 11 and extra-pulmonary type in 4. Results The lesions in all cases located in the posterior basal segments of low lobes. On CT images,the lesions appeared as cystic in 8 cases, solid in 4,cystic-solid in 3. Abnormal systemic feeding ateries were revealed by thin slice enhanced CT scans. Conclusion The main CT sign of pulmonary sequestration is a soft tissue shadow in the posterior basal segments of low lobes. Contrast-enhanced CT scan can show the supplying ateries of the lesions.
