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 ]
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]
Acute presentation may reveal poorly defined a micro-nodular interstitial pattern and ground-glass opacities in the lower and mid lung zones. In addition to this, subacute presentations may show reticular nodular opacities in mid-to-lower lung zones. [1] Chronic forms may show fibrotic changes and appear like Idiopathic pulmonary fibrosis. [3]
Pneumocystis pneumonia can present with interstitial lung disease, as seen in the reticular markings on this AP chest x-ray. A chest X-ray demonstrating pulmonary fibrosis due to amiodarone. Diagnosis of ILD involves assessing the signs and symptoms as well as a detailed history investigating occupational exposures.
2. Any cavitary lesion - Lucency (darkened area) within the lung parenchyma, with or without irregular margins that might be surrounded by an area of airspace consolidation or infiltrates, or by nodular or fibrotic (reticular) densities, or both. The walls surrounding the lucent area can be thick or thin. Calcification can exist around a cavity.
reticular (crisscrossing lines) companion shadow (lines paralleling bony landmarks) nodular (many small dots) rings or cysts; ground glass; consolidation (diffuse opacity with air bronchograms) location (where is the lesion worst?) upper (e.g., sarcoid, tuberculosis, silicosis/pneumoconiosis, ankylosing spondylitis, Langerhans cell histiocytosis)
Reticular pattern with peripheral traction bronchiectasis or bronchiolectasis; There may be mild ground-glass opacity; Indeterminate for UIP: [4] Predominantly subpleural and basal; Subtle reticular pattern; May have mild ground-glass opacity or distortion (“early UIP pattern”) Findings suggestive of another diagnosis, including: [4]
Reticular or linear patterns may be observed in diagnostic imaging. [7] Pneumonitis may cause subpleural honeycombing, changing the shape of the air spaces in an image, which may be used to identify the respiratory disease. [7] The interlobular septa may also thicken and indicate pneumonitis when viewed on a scan. [7]
