Pulmonary oedema
What type of lesion is this? Can you name it?
Inflammation
Bronchopneumonia - characterised by cranioventral suppurative bronchopneumonia
What are the 3 portals of entry for disease in the lungs?
- Erogenous (inhalation): Infectious agents, toxic gases
- Haematogenous (blood): Infectious agents, toxins
- Direct extension: Penetrating wounds, migrating awns, bites, oesophagus rupture, diaphragm perforation (hardware)
What kind of disease pattern is this?
Alveolar pattern - leaving airways as bronchograms
What are the 5 types of pneumonia?
