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 ...
Pulmonary interstitial emphysema (PIE) is a collection of air outside of the normal air space of the pulmonary alveoli, found instead inside the connective tissue of the peribronchovascular sheaths, interlobular septa, and visceral pleura. (This supportive tissue is called the pulmonary interstitium.)
Pulmonary interstitial emphysema (PIE) is a collection of air inside the lungs but outside the normal air space of the alveoli, found as pneumatoses inside the connective tissue of the peribronchovascular sheaths, interlobular septa, and visceral pleura.
The term "usual" refers to the fact that UIP is the most common form of interstitial fibrosis. "Pneumonia" indicates "lung abnormality", which includes fibrosis and inflammation. A term previously used for UIP in the British literature is cryptogenic fibrosing alveolitis (CFA), a term that has fallen out of favor since the basic underlying ...
Cryptogenic organizing pneumonia; Other names: Bronchiolitis obliterans with organizing pneumonia, idiopathic interstitial pneumonia [1]: Micrograph showing a Masson body (off center left/bottom of the image – pale circular and paucicellular), as may be seen in cryptogenic organizing pneumonia.
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.
However, some patients have worsening symptoms and imaging findings, with further increase in septal thickening, GGOs, and consolidation. These patients may develop lung "white-out" with progression to acute respiratory distress syndrome (ARDS) requiring treatment escalation. [17] [21]
They are suggestive for the diagnosis of congestive heart failure, but are also seen in various non-cardiac conditions such as pulmonary fibrosis, interstitial deposition of heavy metal particles or carcinomatosis of the lung. Chronic Kerley B lines may be caused by fibrosis or hemosiderin deposition caused by recurrent pulmonary edema.
