Diffuse alveolar damage is a histological pattern in lung disease. It is seen in acute respiratory distress syndrome (ARDS),[1] transfusion related acute lung injury (TRALI) and acute interstitial pneumonia (AIP).

Cause

Diffuse alveolar damage is associated primarily with ARDS and TRALI in adults, and hyaline membrane disease in neonates.

It is most commonly associated with infection.[2]

Diagnosis

{{Empty section|date=June 2018}}

Diagnosis of ARDS is based on clinical manifestation and its severity is evaluated with ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FIO2).[3]

Prevalence

It is a common biopsy finding.[4] Through histology, diffuse alveolar damage goes through several stages:

  1. Exudative phase - similar to pulmonary edema. The alveoli become flooded with exudate
  2. Hyaline membrane production. Hyaline membranes are fibrinous structures resulting from organization of the exudate.
  3. Organising phase
