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.
They are more common in older individuals.
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.
