Pneumatosis is the abnormal presence of air or other gas within tissues. [1] In the lungs, emphysema involves enlargement of the distal airspaces, [2] and is a major feature of chronic obstructive pulmonary disease (COPD). Other pneumatoses in the lungs are focal (localized) blebs and bullae, pulmonary cysts and cavities.
These patients were all heavy smokers and considered to have a form of interstitial lung disease. Most were in their 40s and had abnormalities in pulmonary function tests, most commonly reduced diffusion capacity for carbon monoxide (DLCO). Their symptoms generally remained stable (did not worsen) over up to 10 years of follow-up. [7]
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.
The reader then classifies the subject x-ray, often recording the findings on the NIOSH Roentgenographic Interpretation form. The ILO Classification system pertains to pulmonary parenchymal abnormalities ( small and large opacities ), pleural changes ( pleural plaques, calcification, and diffuse pleural thickening ) and other features ...
Pulmonary consolidation; Pneumonia as seen on chest X-ray. A: Normal chest X-ray. B: Abnormal chest X-ray with consolidation from pneumonia in the right lung, middle or inferior lobe (white area, left side of image). Specialty: Pulmonology
Enlargement of the right descending pulmonary artery can indirectly reflect changes of pulmonary hypertension, with a size greater than 16 mm abnormal in men and 15 mm in women. [ 6 ] Appropriate penetration of the film can be assessed by faint visualization of the thoracic spines and lung markings behind the heart.
ACD is typically diagnosed by examination of lung tissue under a microscope, either from lung biopsy or an autopsy. The characteristic findings of misplaced pulmonary veins adjacent to pulmonary arteries, and abnormal alveolar and capillary development confirm the diagnosis. [1] FOXF1 genetic testing is also available, which can confirm the ...
Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs. It is typically defined as an area of hazy opacification (x-ray) or increased attenuation (CT) due to air displacement by fluid, airway collapse, fibrosis , or a neoplastic process . [ 1 ]
