A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. [1] Pulmonary infiltrates are associated with pneumonia, tuberculosis, [citation needed] and sarcoidosis. [2] Pulmonary infiltrates can be observed on a chest radiograph. [citation needed]
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...
Vaping-associated pulmonary injury; Other names: Vaping-associated lung injury, [1] e-cigarette, or vaping, product use associated lung injury (EVALI) [2] CT scan of the chest showing diffuse lung infiltrates found in three cases of vaping-associated pulmonary injury: Specialty: Pulmonology, Intensive care medicine: Symptoms
Idiopathic interstitial pneumonia (IIP), or noninfectious pneumonia [1] are a class of diffuse lung diseases. These diseases typically affect the pulmonary interstitium, although some also have a component affecting the airways (for instance, cryptogenic organizing pneumonitis). There are seven recognized distinct subtypes of IIP. [2]
Broadly, a diffuse pattern of GGO can be caused by displacement of air with fluid, inflammatory debris, or fibrosis. Cardiogenic pulmonary edema and ARDS are common causes of a fluid-filled lung. Diffuse alveolar hemorrhage is a rarer cause of diffuse GGO seen in some types of vasculitis, autoimmune conditions, and bleeding disorders. [6]
Acute lung injury (ALI), also called non-cardiogenic pulmonary edema, is characterized by the abrupt onset of significant hypoxemia and diffuse pulmonary infiltrates in the absence of cardiac failure. The core pathology is disruption of the capillary-endothelial interface: this actually refers to two separate barriers – the endothelium and ...
Idiopathic pulmonary fibrosis; Other names: Fibrosing alveolitis, cryptogenic fibrosing alveolitis, diffuse fibrosing alveolitis, usual interstitial pneumonitis, diffuse interstitial pneumonitis: Figure A shows the location of the lungs and airways in the body. The inset image shows a detailed view of the lung's airways and air sacs in cross ...
In addition, a biopsy of the lung that shows organizing diffuse alveolar damage is required for diagnosis. This type of alveolar damage can be attributed to nonconcentrated and nonlocalized alveoli damage, marked alveolar septal edema with inflammatory cell infiltration, fibroblast proliferation, occasional hyaline membranes, and thickening of ...
