Study Notes

Fibrinous Inflammation

  • Characterized by the deposition of fibrin in extracellular spaces
  • Occurs in cases of severe injuries with high vascular permeability, allowing larger molecules like fibrinogen to escape the endothelial barrier
  • Examples of fibrinous exudate locations include meninges, pericardium, and pleura
  • Fibrinous pericarditis is a type of fibrinous inflammation, featuring deposits of fibrin on the pericardium
  • Fibrin exudate forms a pink meshwork that overlays the pericardial surface
