Chest

X-ray

Marked hyperinflation of the lungs and flattening of hemidiaphragms are noted.

Chest

CT

Emphysematous changes are seen predominantly in upper zones of each lung and more extensive on the right side.

Case Discussion

Pulmonary emphysema is an abnormal permanent enlargement of the airspaces distal to the terminal bronchioles associated with destruction of the alveolar wall. 

Centrilobular emphysema is the most frequent type of pulmonary emphysema which affects the proximal respiratory bronchioles, particularly of the upper zones. Centrilobular emphysema is associated with smoking.
