lower lobes or the right middle lobe most frequently involved

In the era before antibiotics, 4 stages used to be seen

Congestion:
the affected lobe is heavy, red, and boggy
M/E vascular congestion with proteinaceous fluid, numerous neutrophils containing the typical gram-positive, lancet-shaped diplococci

red hepatization
lobe has a liver-like consistency
alveolar spaces are packed with neutrophils, red cells, and fibrin

gray hepatization
lung is dry, gray, and firm, because the red cells are lysed, while the fibrinosuppurative exudate persists

Resolution
exudates within the alveoli are enzymatically digested to produce granular, semifluid debris that is resorbed, ingested by macrophages, coughed up, or organized by fibroblasts
pleuritis may similarly resolve or undergo organization, leaving fibrous thickening or permanent adhesions.
M/E of bronchopneumonia shows
focal suppurative exudate that fills the bronchi, bronchioles, and adjacent alveolar spaces.

Complications of pneumonia

Lung abscess
Empyema thoracic
Organisation
Bacteremia, causing meningitis, septic arthritis or infective endocarditis
