Image 2

Find 2 examples of traction bronchiectasis in the left lung.

Find 2 example of traction bronchiolectasis in the left lung.

Find an area of ground-glass opacity not associated with honeycombing in each lung.

Note how areas of traction bronchiectasis and bronchiolectasis blend into regions of honeycomb lung. These features indicate advanced fibrosis and irreversible disease.

b) Traction bronchiectasis. At the periphery of the lung, dilated bronchioles constitute traction bronchiolectasis.
c) Ground-glass opacity representing areas of inflammation or early fibrosis
f) Honeycombing
g) Architectural distortion, indicated by honeycombing and traction bronchiectasis
