"CT shows the affected lung as being hyperlucent with diminished vascularity. The disease can be unilateral or bilateral. The entire lung can be affected, however, there can also be lobar, segmental, and subsegmental involvement in a patchy distribution 2.

Bronchiectasis may be present, although this is not a universal finding 5."
