变应性支气管肺曲霉菌病的HRCT表现

摘要

Objective To explore the HRCT (High-Resolution Computerized Tomography) features of allergic bronchopulmonary aspergillosis (ABPA) so as to have a better understanding of ABPA and improve its accurate diagnostic rate. Methods Retrospective analysis of the HRCT features of 11 clinically-conifrmed ABPA patients was made. Results HRCT revealed central bronchiectasis in 11 cases, bronchial mucus plugs in 9 cases, patchy inifltration shadows in 7 cases, centri-lobular nodules with a tree-in-bud pattern in 6 cases, pleural thickening and mediastinal lymph node enlargement in 3 cases. Conclusion ABPA presents the typical HRCT features of central bronchiectasis accompanied with bronchial mucus plugs, based on which it can be diagnosed in combination with clinical and laboratory examinations.%目的：探讨变应性支气管肺曲霉菌病（ABPA）的HRCT影像学特点，以提高对该病的认识及诊断准确率。方法回顾性分析11例经临床确诊的ABPA患者的HRCT影像学表现。结果11例患者的HRCT表现主要为中心性支气管扩张11例，支气管粘液栓形成9例，斑片状浸润阴影7例，树芽征为特征的小叶中心结节形成6例，3例伴有胸膜局限性增厚和纵膈淋巴结增大。结论ABPA的HRCT表现具有特征性，即以中心性支气管扩张为主并多伴有支气管腔内粘液栓形成，可据此影像学特点结合临床及实验室检查进行诊断。
