• 
  This gross photograph of lung taken at autopsy demonstrates the degree of emphysematous change (arrows). Also note that the rest of the lung is consolidated, indicating a pneumonia.
• 
  This is a higher-power view of the lung showing the emphysematous change.
• 
  This low-power photomicrograph of the lung demonstrates the enlarged air spaces indicative of emphysematous change.
• 
  This higher-power photomicrograph of the lung shows more clearly the enlarged air spaces indicative of emphysematous change.
• 
  This gross photograph of the heart taken at autopsy demonstrates right ventricular hypertrophy and dilatation (arrows).

Consolidation is the filling of lung air spaces with exudate--this is a sign of pneumonia.

In alcoholics, aspiration pneumonia is common--bacteria enter the lung via aspiration of gastric contents.
