Ground-glass opacity is a finding seen on chest x-ray or computed tomography imaging of the lungs. It is typically defined as an area of hazy opacification or increased attenuation due to air displacement by fluid, airway collapse, fibrosis, or a neoplastic process. When a substance other than air fills an area of the lung it increases that area's density. On both x-ray and CT, this appears more grey or hazy as opposed to the normally dark-appearing lungs. Although it can. UIP may be diagnosed by a radiologist using computed tomography (CT) scan of the chest, or by a pathologist using tissue obtained by a lung biopsy Hypersensitivity pneumonitis: correlation of individual CT patterns with functional abnormalities.

Chronic hypersensitivity pneumonitis: differentiation from idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia by using thin-section CT In two patients, CT revealed concurrent preexisting disease (hypersensitivity pneumonitis, n = 1; silicosis, n = 1) (six observers). CO-RADS category 2 assessments were false-negative for COVID-19 in 22 of 159 ratings (average, 13.8%; 95% CI: 9%, 18%) in 13 cases, including all four false-negative cases with a CO-RADS 1 score.

Although it is primarily defined as an idiopathic disease, the morphologic pattern of NSIP is encountered in association with frequent disorders, such as connective tissue diseases, hypersensitivity pneumonitis, or drug exposure (, 26 27). Once the morphologic pattern of NSIP has been determined in a patient, these secondary forms of NSIP must be ruled out by the clinician
Cryptogenic organizing pneumonia (COP), formerly known as bronchiolitis obliterans organizing pneumonia (BOOP), is an inflammation of the bronchioles (bronchiolitis) and surrounding tissue in the lungs. It is a form of idiopathic interstitial pneumonia..

Progressive massive fibrosis (PMF) refers to the formation of large mass-like conglomerates, predominantly in the upper pulmonary lobes, associated with radiating strands.These classically develop in the context of certain pneumoconioses (especially coal worker's pneumoconiosis and silicosis) although similar mass-like densities have occasionally been described with talcosis Nipple markers can be a useful technique in the evaluation of small radiodensities overlying the expected position of the nipple on a chest radiograph. Not uncommonly a small round opacity projects over the lower thorax on a chest radiograph (see: solitary pulmonary nodule).. Often, especially in women, this is a nipple shadow - a dense nipple projected over the lung

Immunotherapy is becoming a standard of care for many cancers. Immune-checkpoint inhibitors (ICI) can generate immune-related adverse events. Interstitial lung disease (ILD) has been identified as a rare but potentially severe event. Between December 2015 and April 2016, we conducted a retrospective study in centres experienced in ICI use. We report the main features of ICI-ILD with a focus. 1 Definition.
