Scar vs. Atelectasis: "bibasilar linear opacity" is a term used by radiologists to describe thin lines seen in the bases of both lungs. The typical cause for this are benign conditions such as atelectasis or scarring after a previous infection (pneumonia) . Comparison with previous chest x-rays to determine chronicity and/or cause may be necessary.
