摘要
目的:探讨胸部X线平片、螺旋CT对肺隔离症的诊断价值。方法:搜集经手术病理、数字减影血管造影(DSA)证实的24例肺隔离症病人,其中叶内型22例,叶外型2例(包括膈下1例)。所有病例都有胸部正侧位平片及CT平扫、增强扫描,1例行数字减影血管造(DSA)检查。结果:患者胸部平片表现为肺内结节、团块状影(19例),囊性病变(5例)。CT表现为含气体或液体的囊肿或软组织肿块(20例),病变周围见肺气肿(4例)。螺旋CT对异常供血血管显示率为75%。结论:胸部X线平片对肺隔离症的发现及定位有价值,螺旋CT,尤其是增强螺旋CT加多平面重建技术(MPR)和曲面重建技术(CPR)能清楚显示主动脉异常供血血管,且对肺部病变的评价具有其它检查无可比拟的优越性,是肺隔离症的最有效影像学检查手段。
Aim： To explore the chest X-ray plain film and spiral CT diagnostic value of pulmonary sequestration, Methods： Collecting 24 eases of pulmonary sequestration confirmed by surgery, pathology and Digital subtraction angiography （ DSA）, in which 22 cases of intralobar type, 1 case of extralobar type and I ease below the diaphragm. All eases had examinations with chest plain films, CT plain scan and enhanced CT scan, 1 case did DSA inspection. Results： Chest plain films showed lung nodule, mass shadow （17 cases） or cystic lesion （4）. CT showed 17 cases presented as cysts containing gas or liquid, or soft tissue masses, and 4 cases of disease had been wrapped by emphysema, CT rate for the abnormal supply blood vessels was 75%. Conclusion：The chest X-ray film has the value of discovery and location of pulmonary sequestration, spiral CT, especially the enhanced CT plus multi planar reformation （MPR） and curved planar reformation （CPR） clearly show the aortic abnormal supply blood vessels, and their evaluation of lung disease have unparalleled advantages compared with other check, they are the most effective means of imaging.
