CT增强扫描无创性评价肺隔离症的价值

Contrast-enhanced CT for non-invasive evaluation of Bronchopulmonary Sequestration

目的探讨CT增强扫描对肺隔离症的诊断价值。方法对19例肺隔离症患者CT增强扫描进行回顾性分析，所有患者均经手术或主动脉造影证实。结果19例肺隔离症中有17例为肺叶内型，2例为肺叶外型，19例患者的病灶均位于两下肺。呈囊性病灶6例，实性病灶5例，囊实性病灶8例，病灶周围有肺气肿11例。其中18例CT显示供血动脉。结论CT增强扫描清晰显示肺隔离症结节或肿块内部的囊实性成分及异常的主动脉供血血管，是无创性评价肺隔离症的首先检查方法。

Purpose： To evaluate the diagnostic value ofcontrast-enhanced CT in bronchopulmonary sequestration.. Materials and Methods： The contrast-enhanced CT of 19 patients of pulmonary sequestration were retrospective studied. They all were proved by surgery or angiography. Results： In the 19 patients, there are 17 intralober sequestration and 2extralober sequestration. All 19 cases located in right or left lower lobar. 6 of them were cystic, 5 were solid and 8 were cystic and solid. The emphysema around the lesions was showed in 11cases. Contrast-enhanced CT successfully delineated the origin and course of anomalous systemic artery.Conclusion： Contrast-enhanced CT scan demonstrated the cystic and solid contents in nodules and masses, and also be helpful to identify anomalous systemic artery. Contrast-enhanced CT is the first choose in the noninvasive diagnosis of bronchopulmonary sequestration.
