Pleuritis

  • Inflammation of the pleura
  • Common in animals
  • Inflammatory agents reach the pleura by:
  • Common acute forms:
    • Purulent
    • Fibrinous
      • Common sequele:
        • Organising fibrinous pleuritis in which the visceral pleura becomes enveloped in a restrictive fibrous blanket
        • Pleural adhesions, especially common in ruminants and pigs
  • Granulomatous pleuritis may cause hypertrophic osteopathy
