先天性支气管闭锁的多层螺旋CT诊断

目的探讨先天性支气管闭锁的多层螺旋CT表现。方法回顾性分析我院收治的15例先天性支气管闭锁的病例,男7例,女8例,年龄6~44岁,分析多层螺旋CT上病变的位置、边界,病灶内支气管及肺血管情况,占位效应等特征。结果先天性支气管闭锁发生于上肺病灶11例,下肺病灶6例。单个肺段发生11例,多个肺段发生4例,上、下肺同时发生2例,上、中肺1例,两上肺1例。所有病例病灶表现为局限性透亮度增高区,与正常肺组织分界欠清,其内肺血管细小,可见正常肺组织呈尖角状突入病灶内。所有病变内均见支气管扩张,合并支气管黏液栓11例,＂指套征＂8例。病灶具占位效应11例。合并感染3例,先天性肺气道畸形2例。结论支气管闭锁为...

Summary:目的探讨先天性支气管闭锁的多层螺旋CT表现。方法回顾性分析我院收治的15例先天性支气管闭锁的病例,男7例,女8例,年龄6~44岁,分析多层螺旋CT上病变的位置、边界,病灶内支气管及肺血管情况,占位效应等特征。结果先天性支气管闭锁发生于上肺病灶11例,下肺病灶6例。单个肺段发生11例,多个肺段发生4例,上、下肺同时发生2例,上、中肺1例,两上肺1例。所有病例病灶表现为局限性透亮度增高区,与正常肺组织分界欠清,其内肺血管细小,可见正常肺组织呈尖角状突入病灶内。所有病变内均见支气管扩张,合并支气管黏液栓11例,＂指套征＂8例。病灶具占位效应11例。合并感染3例,先天性肺气道畸形2例。结论支气管闭锁为支气管树的先天性发育畸形,可持续至成人期。当肺野内局限性肺过度充气特别是合并管状、指套状密影,以及肺血管细小时需考虑到支气管闭锁。

Objective To summarize the multi-slice CT findings of congenital bronchial atresia.Methods CT features including lesion location,margin,bronchi and vessels inside the lesion,and mass effect were reviewed in 15 consecutive patients with congenital bronchial atresia.Results The 17 lesions were located in the upper lobe（11）and lower lobe（6）involving one segment（11）or multiple segments（4）.All lesions were low attenuating with ill-defined margin,small vessels,and wedge-shaped normal lung extending into the lesions.Other features included bronchiectasis with mucus impaction（11）and finger-in-glove appearance（8）,mass effect（11）,infection（3）and congenital airway malformation（2）.Conclusion Bronchial atresia should be considered on CT when hyperinflated lung is accompanied with finger-in-glove sign and decreased pulmonary vessels.
