*Can have morphological similarity to emphysema (below), however, it occurs in different situations with differing aetiology and implications
*Described as: "a condition of the lung characterised by an increase beyond normal in size of air spaces distal to the terminal bronchiole without destructive changes in the alveolar walls"
*It can arise in two ways :
**'''Obstructive'''
***Follows a "check-valve" type lesion in bronchi or bronchioles - the size of the overinflated area will obviously depend on the location of the obstruction, e.g. ''M. apri'' in pigs
**'''Non-obstructive'''
***Occurs when other lung units are decreased in size e.g. in enzootic pneumonia
