Check for errors and try again. 1986;146 (3): 477-83. Pneumonia; Pulmonary embolism: infarction or intrapulmonary hemorrhage Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. Nodules between 2 and 7 millimeters may represent acute hypersensitivity pneumonitis, whereas nodules between 7 and 30 millimeters tend to be lung granulomas or metastases. multifocal patchy ground-glass opacities. Airspace or patchy opacities may represent consolidation, atelectasis or mucoid impaction. Lung opacities may gradually resolve over six months without radiological sequelae or with minimal damage . Parasitic infections of the lung occur worldwide among both immunocompetent and immunocompromised patients and may affect the respiratory system in a variety of ways. Nonspecific interstitial pneumonia: evolving concepts. Usual interstitial pneumonia (UIP) is a histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF).. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and an apicobasal gradient of peripheral septal thickening, bronchiectasis, and honeycombing.

It is considered the most common cause of eosinophilic lung disease in developed countries 13. The three common patterns seen are patchy or airspace opacities; linear opacities; and nodular or dot opacities. [] Rounded lesions measuring more than 3 cm in diameter are termed lung masses and should be considered 7. The French terms "envole de ballons" and "lcher de ballons", which translate to "balloons release", are also used to describe this same appearance. In all cases, respiratory bronchiolitis-interstitial lung disease is typically associated with heavy tobacco smoking (usually of 30 pack-years or more) and is often seen in young middle-aged patients (30-40 years of age)..

COVID-19 pneumonia represents a maximum medical challenge due to the virus’s high contagiousness, morbidity, and mortality and the still limited possibilities of the health systems. A CT scan may show mosaic attenuation, air trapping, bronchial thickening, bronchiectasis, atelectasis and/or mucoid Low diffusing capacity of the lung for carbon monoxide (D LCO) was associated with bronchial wall thickening and linear opacities. Involvement tends to be subpleural and generally symmetrical with an apicobasal gradient. Pulmonary collapse may be seen as a consequence of endobronchial mucoid impaction.

In recent years, the use of immune checkpoint inhibitor (ICI) therapy has rapidly grown, with increasing U.S. Food and Drug Administration approvals of a variety of agents used as first- and second-line treatments of various malignancies. Epidemiology. The lung volume is usually unchanged, but may be smaller with pulmonary fibrosis.

In approximately a third of patients, the presentation may mimic pulmonary infection 6. Historically, non-specific interstitial pneumonia was divided into three groups; however, due to similar outcomes, groups II and III (mixed cellular and fibrotic and mostly fibrotic, respectively)are now both classified as fibrotic type: Important negative histological findings are the absence of acute lung injury, including hyaline membranes, granulomas, organisms or viral inclusions, dominant airways disease or organizing pneumonia, eosinophils and coarse fibrosis. This review provides an update on the presenting symptoms, signs, investigation and management of diseases affecting the lung caused by protozoa, nematodes and trematodes.

Opacities seen in a child with acute asthmatic exacerbation but without high fever, chest pain, or leukocytosis are much more likely to be caused by atelectasis than pneumonia.

Clinical presentation is with the expected recurrent bacterial infections and hemoptysis.Patients have a chronic cough and expectorate copious quantities of sputum, frequently blood stained and containing mucous plugs 2,7.. Later in the disease, larger volume hemoptysis, which may be life-threatening, as well as pneumothoraces become more drugs or organic allergens 12. 6. Possible causative agents include radiation therapy of the chest, exposure to medications used during chemo-therapy, the inhalation of debris (e.g., animal dander), aspiration, herbicides or fluorocarbons and some systemic diseases.
