Parenchymal bands are a HRCT finding. They can be commonly encountered among patients with asbestosis.
They are typically over 2 cm in length (up to 5 cm), 1-3 mm thick and run through the lung parenchyma and usually extend from a visceral pleural surface.
They are formed in a number of ways. They are thought to reflect pleuroparenchymal fibrosis and are usually associated with distortion of the lung architecture.
To mention a few causes:
Asbestosis - found in 60% of patients.
Sarcoidosis
Silicosis
Systemic lupus erythematosus
Pulmonary fibrosis
Ankylosing spondylitis
