摘要
目的分析变态反应性支气管肺曲霉菌病(ABPA)的MSCT特点。方法回顾性分析我院临床确诊的25例ABPA患者的影像学及临床资料。结果 25例患者均表现为中央型支扩。23例合并粘液栓,呈牙膏状、指套状、树枝状分布。两肺上叶受累19例,右肺中叶受累7例,左肺下叶受累4例。15例粘液栓的CT值大于同层面胸椎旁肌肉的CT值,4例CT值大于100HU。22例可见小叶中心结节和树芽征;25例均合并不同程度的肺炎,17例伴肺实变或肺不张。结论 ABPA具有一定的CT诊断特点,上叶中心性支气管扩张、支气管粘液栓嵌塞、高密度粘液栓、小叶中心结节、树芽征等征象有助于其诊断。
Objective To evaluate the MSCT appearance of allergic bronchopulmonary aspergillosis （ABPA）. Methods The MSCT and clinical data of 25 patients with clinically confirmed ABPA in our hospital were analyzed retrospectively. Results All patients showed central bronchiectasis; mucus plugs were found in 23 cases presenting with toothpaste, finger and dendritic distribution. Bilateral upper lobes involvement （n = 19）, right middle lobe involvement （n = 7 ）, left lower lobe involvement （n =4） were classified. The CT attenuation of mucous plugs in 15 cases was greater than the density of the same level of thoracic muscle, in which 4 cases were greater than I00 HU. Other features included tree-in-bud sign and centrilobular nodules in 22 ca- ses, accompanying with pneumonia in all eases, and pulmonary consolidation or atelectasis in 17 cases. Conclusion The char- acteristic manifestions of ABPA on CT are central bronchiectasis of upper lobes, mucoid plug impaction （ usually high attenua- tion）, tree-in-bud sign and centrilobular nodule, which can facilitate for the diagnosis of ABPA.
