Yes: Although it was 20 years ago, it is possible to have areas of lung that are not fully aerated on a chronic type basis. Often called atelectasis. This could be what is described by "groundglass density" The best way to tell is with direct comparison of the old CT scan to a new one. It is also possible that this area represents a more recent area of pneumonia. See if a comparison can be done.
