76-year-old female with apoplexy; terminal presentation with pyrexia,
dyspnoea and crepitations. Autopsy specimen.
Macroscopically: grey-yellow clusters of varying size, partly confluent.
Fragile lung tissue, the effusion appears dull, increased consistency
due to alveoli without air
- Alveoli and bronchi filled with numerous granulocytes and fibrin
- Clusters of alveolar macrophages
- Hyperaemia (active in inflammation, passive in heart failure)
in the area of alveolar septa
- Possible fibrinous or fibrinous-pyogenic pleuritis
Typical inflammatory foci with bronchiolitis in the centre and
pus in the neighbouring alveoli. Recent and older, ie chronically
carnified clusters can occur next to each other. The clusters can
become confluent and create the impression of a lobar pneumonia
