Osteophyte-induced adjacent pulmonary atelectasis and fibrosis are typically seen as focal pulmonary interstitial opacities adjacent to thoracic spinal osteophytes. They are a relatively common finding in thoracic CT imaging.
On this page:
Epidemiology
They are more common in older individuals.
Pathology
They are thought to represent a variable combination of compressive atelectasis ± fibrosis (focal pulmonary fibrosis).
Location
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 commonly located.
Some studies have suggested that the likelihood of lung fibrosis is commensurate with the size of the osteophyte 3. Subpleural fat is considered a protective measure against osteophyte-induced lung fibrosis.
Treatment and prognosis
Most are not thought to be of clinical significance, generally do not appear to progress, and are not considered a pre-clinical form of more extensive fibrosing lung disease 2.
