What does it mean, when my chest ct scan shows that i have multiple patches of ground glass infiltrates, and should i be worried because my doctor isn?

Could be scar tissue: It may be due to scar tissue in your lungs from a recent infection or chronic scarring from prior irritation to the lungs from tobacco or chemical exposures. As long as your breathing tests are stable, the approach is usually to watch it and see if it resolves over time with future scans.

Probably chronic : Usually these are findings due to prior swelling or infection in lungs; even based on where you grew up. We use stability on cts to confirm benign nature. Sometimes treatment w/ antibiotics considered. Biopsy considered with hi risk though age & smoking history important.
