Pleural plaques are patchy collections of hyalinized collagen in the parietal pleura. [2] They have a holly leaf appearance on X-ray . [ 1 ] They are indicators of asbestos exposure, and the most common asbestos-induced lesion. [ 3 ]
CT scans can more readily differentiate whether pleural thickening is due to extra fat deposition or true pleural thickening than X-rays. [3] If a fibrothorax is severe, the thickening may restrict the lung on the affected side causing a loss of lung volume. [7] Additionally, the mediastinum may be physically shifted toward the affected side. [3]
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
The goal of treatment with immunosuppressive agents such as corticosteroids is to decrease lung inflammation and subsequent scarring. Responses to treatment vary. Those whose conditions improve with immunosuppressive treatment probably do not have idiopathic pulmonary fibrosis, for idiopathic pulmonary fibrosis has no significant treatment or cure.
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...
In rounded atelectasis (folded lung or Blesovsky syndrome [15]), an outer portion of the lung slowly collapses as a result of scarring and shrinkage of the membrane layers covering the lungs (pleura), which would show as visceral pleural thickening and entrapment of lung tissue. This produces a rounded appearance on X-ray that doctors may ...
Idiopathic pulmonary fibrosis (IPF) synonymous with cryptogenic fibrosing alveolitis [5] is a rare, progressive illness of the respiratory system, characterized by the thickening and stiffening of lung tissue, associated with the formation of scar tissue.
