Osteophyte induced adjacent pulmonary atelectasis and fibrosis

Osteophyte induced adjacent pulmonary atelectasis and fibrosis are typically seen as focal pulmonary interstitial opacities adjacent to thoracic spinal osteophytes. They can be a relatively common finding in thoracic CT imaging.

They are more common in older individuals.

They are thought to represent a variable combination of compressive atelectasis +/- fibrosis (focal pulmonary fibrosis).

They are typically seen involving the medial basal segment of the right lower lobe and posterior segment of the left lower lobe where osteophytes are more common. 

Most are not thought to be of clinical significance and generally do not appear to progress and are not considered a pre-clinical form of more extensive fibrosing lung disease 2.
