Allergic Bronchopulmonary Aspergillosis-HRCT
Bronchiectasis and peribronchial thickening are the most common CT findings in ABPA. ABPA typically involves the segmental and subsegmental bronchi, particularly those in the upper lobes. High-attenuating mucoid impaction is a characteristic finding. Mucus plugging of the small airways can be observed on high-resolution CT scans, with resultant centrilobular nodularity and the tree-in-bud sign.
