Parenchymal bands

linear opacities, 25 cm in length, seen in patients with pulmonary fibrosis or other causes of interstitial thickening. They are often peripheral and generally contact the pleural surface. Parenchymal bands can represent contiguous thickened interlobular septa, peribronchovascular fibrosis, coarse scars or atelectasis associated with lung or pleural fibrosis. They are most common in patients with asbestos-related pleural thickening, asbestosis and sarcoidosis.
