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 ]
2. Discrete nodule(s) without calcification—One or more nodular densities with distinct borders and without any surrounding airspace opacification. Nodules are generally round or have rounded edges. These features allow them to be distinguished from infiltrates or airspace opacities. To be included here, these nodules must be noncalcified.
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]
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] Other predominant distribution: Peribronchovascular; Perilymphatic; Upper or mid-lung ...
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
"In other words, it is generally a mild condition." The disease can be treated with some antibiotics. There are ways to avoid getting or spreading the disease using the same precautions you would ...
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung.
