Clusters of cystic spaces of variable size in all lobes of the right lung, most pronounced in the basal segments of the lower lobe. These are thin walled and largely distributed around the distal bronchioles.
The right lung is reduced in volume with smaller and reduced vascular markings with peripheral pruning. This gives a radiolucent appearance to the right lung.
Compensatory hyperinflation of the left lung.
Bronchial wall thickened and bronchoceles in the basal segments.
