Panlobular emphysema is a morphological descriptive type of emphysema that is depicted by permanent destruction of the entire acinus distal to the respiratory bronchioles with no "obvious" associated fibrosis. PathologyPanacinar emphysema is characterized by permanent destruction of the airspaces (alveoli) distal to the respiratory bronchioles.

Peribronchovascular consolidation is a form of consolidation which tends to occur along peribronchovascular bundles. If smooth and mild, it may be seen as peribronchovascular thickening on chest radiography and in some instances on CT. If more extensive it tends to occur as more mass like areas of opacification occurring with a peribronchovascular distribution.
