支气管扩张症合并肺出血的影像学表现

Imaging appearances of bronchiectasis complicated by pneumorrhagia

目的 :探讨支气管扩张症合并肺出血的影像学表现及病理基础。方法 :对 2 5例支扩合并咯血患者行常规胸部X线、CT及高速螺旋CT (HRCT)检查。结果 :平片表现局限性或弥漫性片絮状淡薄阴影 12例。短期再次摄片 ,病变吸收变化 9例 ,1例进展增多。HRCT证实为支气管扩张症 ,其中柱状 12例 ,静脉曲张型 9例 ,囊状 8例。诊断为支扩合并肺出血 13例。结论 :影像学 ,尤其是动态影像学观察对发现支扩合并肺出血很敏感 ,可以为临床诊断。

Objective:To study imaging appearances and pathological basis of bronchiectasis complicated by pneumorrhagia Methods:25 patients with hempotysis performed routine chest radiography,CT scanning and HRCT scanning Results:The categories of all cases were cylindrical (12 case),varicose (9 cases) and sacular (8 cases) in 25 patients with bronchiectasis There are 13 cases combining with pneumorrhagia Local or diffuse lung opacity were seen on plain film in these patients The lesions have been absorbed at short intervals in 12 patients,one case became aggravating Conclusion:Chest radiography and HRCT are not only especially valuable to observe the morphology changes of bronchiectasis complicated by pneumorrhagia but also provide information for clinical diagnosis and treatment
