Last reviewed 07/2023
Pulmonary fibrosis is a condition in which there is diffuse fibrosis of lung parenchyma with a resultant impairment of gas transfer and ventilation-perfusion mismatching.
Fibrosis within the lung may be:
- replacement fibrosis, secondary to disorders such as:
- infarction
- pneumonia
- tuberculosis
- focal fibrosis, in response to irritants such as:
- silica
- coal dust
- interstitial fibrosis:
- cryptogenic (idiopathic) fibrosing alveolitis
- extrinsic allergic alveolitis
