Can pulmonary fibrosis affect young children?

Rare: This would be rare. It could happen following a severe lung infection that caused lung injury and it could be a consequence of prolonged exposure to high oxygen concentrations as might happen to a premature infant. Fortunately infants and small children are still creating new lung that eventually makes up for the areas fibrosed.

Unusual : Rarely in presence of connective tissue disorders, after certain medications, after chest radiation.
