Objective To investigate the chest radiographic and computed tomographic manifestations of allergic bronchopulmonary aspergillosis (ABPA). Method We retrospectively analyzed the chest radiographic and computed tomographic manifestations of 20 ABPA patients treated between December 2005 and December 2013. Results Chest radiograph showed that there were 4 negative cases, 14 cases of solid mass, 10 cases of increased and disorder of bronchovascular shadows, and 5 cases of bronchiectasis. Chest computed tomography showed that there were one negative case, 18 cases of bronchiectasis, 17 cases of central bronchiectasis among which central and peripheral bronchi were involved in 6 cases and 1 case presented as pure peripheral bronchiectasis, 11 cases of tree-in-bud signs, 6 cases of mucous embolism, 8 cases of solid mass, 5 cases of ground-glass opacity, 4 cases of pleural thickening, 3 cases of pleural effusion, and 2 cases of atelectasis. Conclusions For asthma and cystic fibrosis patients, central bronchiectasis on chest CT indicates the diagnosis of ABPA, but it cannot be considered as a characteristic feature. Bronchiectasis combined with high attenuation mucus may be a characteristic feature of ABPA although it is rare.
