Ground-glass opacity is in contrast to consolidation, in which the pulmonary vascular markings are obscured. [3] [5] GGO can be used to describe both focal and diffuse areas of increased density. [5] Subtypes of GGOs include diffuse, nodular, centrilobular, mosaic, crazy paving, halo sign, and reversed halo sign. [6]
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 ...
The increased fluid in the lungs leads to increased airway resistance and reduced lung compliance. It is thought this could be from lower levels of circulating catecholamines after a caesarean section, which are believed to be necessary to alter the function of the ENaC channel to absorb excess fluid from the lungs. Pulmonary immaturity has ...
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 ...
A chest X-ray will show fluid in the alveolar walls, Kerley B lines, increased vascular shadowing in a classical batwing peri-hilum pattern, upper lobe diversion (biased blood flow to the superior parts instead of inferior parts of the lung), and possibly pleural effusions. In contrast, patchy alveolar infiltrates are more typically associated ...
lung volume increased (e.g., Langerhans cell histiocytosis, lymphangioleiomyomatosis, cystic fibrosis, allergic bronchopulmonary aspergillosis) decreased (e.g., fibrotic lung disease, chronic sarcoidosis, chronic extrinsic allergic alveolitis) Pleural effusions may occur with cancer, sarcoid, connective tissue diseases and ...
Good vascular function is important because it means a person’s blood vessels are able to expand and contract so their blood can flow efficiently, delivering oxygen and nutrients to the body and ...
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
