Answer

Diagnostic signs on chest radiograph include pulmonary infiltrate, mucus plugging and the finger-in-glove sign (ie, distal occlusion of bronchi packed with secretion), and bronchiectasis. Another reason for chest imaging is to look for late changes of lung tissues, such as fibrosis, blebs, bullae, and/or spontaneous pneumothorax. A dilated bronchus is seen as a ring shadow on en face. On a coronal view, the dilated bronchus may be seen as a parallel line shadow. Both are unique to ABPA and ABPM.

Conventional CT scanning provides an axial perspective and can demonstrate proximal and distal bronchiectasis.

Bronchography demonstrates bronchiectasis, but it is associated with complications and generally not necessary since CT scanning is available. Bronchography is not recommended for children because of the need for general anesthesia.
