Osteophyte induced adjacent pulmonary atelectasis and fibrosis are typically seen as focal pulmonary interstitial opacities adjacent to thoracic spinal osteophytes. They can be relatively common finding in thoracic CT imaging. They are commoner in older individuals
Pathology
They are although thought to represent a variable combination of atelectasis +/- fibrosis (focal pulmonary fibrosis). They
Location
They are typically seen involving the medial basal segment of the right lobe and posterior segment of the left lower lobe where osteophytes are commoner in older individuals.
Prognosis
Most are not thought to be of clinical signifcance and generally do not appear to progress and are not considered a pre-clinical form of more extensive fibrosing lung disease3.
