Overview of interstitial lung abnormalities (ILAs). ILAs represent incidental findings on a chest CT scan, which affect more than 5% of any lung zone (upper, middle or lower) in a person where interstitial lung disease / pulmonary fibrosis was not suspected.

Interstitial lung abnormalities can be found in 2-9% of patients who have a CT scan (depending on the population studied). There is no clear consensus on how these should be followed up.

The main problem is that in some cases, ILAs may actually represent an early case of pulmonary fibrosis / interstitial lung disease. Therefore there is a risk that the abnormalities may worsen over time.

This is a useful overview of interstitial lung abnormalities:
