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 ]
Two pharmacological agents intended to prevent scarring in mild idiopathic fibrosis are pirfenidone, which reduced reductions in the 1-year rate of decline in FVC and reduced the decline in distances on the 6-minute walk test, but had no effect on respiratory symptoms, [31] and is nintedanib, which acts as an antifibrotic, mediated through the ...
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 ...
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]
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 is interstitial lung disease for which no obvious cause can be identified (idiopathic) and is associated with typical findings both radiographic (basal and pleural-based fibrosis with honeycombing) and pathologic (temporally and spatially heterogeneous fibrosis, histopathologic honeycombing, and fibroblastic foci).
Paracicatricial emphysema, also known as irregular emphysema, is seen next to areas of fibrosis (scarring) as large spaces. The scarring is most often a result of silicosis, granulomatous infection, tuberculosis, or pulmonary infarction. It can be difficult to differentiate from the honeycombing of pulmonary fibrosis. [29]
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring (pulmonary fibrosis) involves the pulmonary interstitium (the supporting framework of the lung). UIP is thus classified as a form of interstitial lung disease.
