What are the locations most affected by lung bronchiectasis?
Generally, this type of pathology compromises the inferior lung regions, such as the basal segments of the lower lobes, middle lobe and lingular segment.
What are the main causes of bronchiectasis in the upper lobes?
Bronchiectasis preferably located in the upper lobes are related to previous tuberculous infections, allergic bronchopulmonary aspergillosis, or bronchial obstruction.
CT scout: similarly to an x-ray, the scout shows ring shadows and interstitial markings predominantly involving the left lung lower zones.
CT confirms diffuse bronchial wall thickening, peripheral mucoid impaction and cystic bronchiectasis severely distorting the left lower lobe. Centrilobular nodules in a tree in bud distribution within the lower lobes are likely related to acute bronchial infection/aspiration.
