- Diffuse parenchymal lung diseases, often collectively referred to as the interstitial lung diseases (ILDs), are a heterogeneous group of disorders that are classified together because of similar clinical, roentgenographic, physiologic, or pathologic manifestations (show table ) .
- This manifests clinically as a limitation in the ability of the lungs to transfer oxygen from the alveoli to the pulmonary capillary bed.
- However, the term interstitial is misleading, since most of these disorders are also associated with extensive alteration of alveolar and airway architecture.
