A 28-year-old female asked:

It most: likely is not significant, and simply related to gravity and/or a less than complete depth of inspiration at the moment of the scan. Atelectasis in this case means that small portions of the lung are not filled with air/collapsed. It is relatively common as an incidental finding on CT.
