  2. Ground-glass opacity - Wikipedia

    en.wikipedia.org/wiki/Ground-glass_opacity

    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]

  3. Antisynthetase syndrome - Wikipedia

    en.wikipedia.org/wiki/Antisynthetase_syndrome

    One study showed that reticulation, ground glass opacities, and traction bronchiectasis are the most common CT scan features of antisynthetase syndrome. [40] The presence of organizing pneumonia and non-specific interstitial pneumonia is somewhat common in antisynthetase syndrome. [41]

  4. Usual interstitial pneumonia - Wikipedia

    There may be superimposed CT features such as mild ground-glass opacity, reticular pattern and pulmonary ossification. Probable UIP pattern: [4] Predominantly subpleural and basal; Often heterogenous distribution; Reticular pattern with peripheral traction bronchiectasis or bronchiolectasis; There may be mild ground-glass opacity; Indeterminate ...

    en.wikipedia.org/wiki/Interstitial_lung_disease

    Interstitial lung disease affects gas flow in the alveoli The alveoli Micrograph of usual interstitial pneumonia (UIP). UIP is the most common pattern of idiopathic interstitial pneumonia (a type of interstitial lung disease) and usually represents idiopathic pulmonary fibrosis. H&E stain. Autopsy specimen.

  6. Desquamative interstitial pneumonia - Wikipedia

    en.wikipedia.org/wiki/Desquamative_interstitial...

    Desquamative interstitial pneumonia (DIP) is a type of idiopathic interstitial pneumonia featuring elevated numbers of macrophages within the alveoli of the lung. [1] DIP is a chronic disorder with an insidious onset. Its common symptoms include shortness of breath, coughing, fever, weakness, weight loss, and fatigue.

  7. Idiopathic pulmonary fibrosis - Wikipedia

    en.wikipedia.org/wiki/Idiopathic_pulmonary_fibrosis

    Ground-glass opacities are common but less extensive than the reticulation; Distribution characteristically basal and peripheral though often patchy. High-resolution computed tomography scans of the chest of a patient with IPF. The main features are of a peripheral, predominantly basal pattern of coarse reticulation with honeycombing

  8. Cryptogenic organizing pneumonia - Wikipedia

    en.wikipedia.org/wiki/Cryptogenic_organizing...

    On high resolution computed tomography, airspace consolidation with air bronchograms is present in more than 90% of patients, often with a lower zone predominance. A subpleural or peribronchiolar distribution is noted in up to 50% of patients. Ground glass appearance or hazy opacities associated with the consolidation are detected in most patients.

  9. Lung nodule - Wikipedia

    en.wikipedia.org/wiki/Lung_nodule

    Ground glass opacity: No routine follow-up: CT after 6–12 months to check if persistent, then after 2 years and then another 2 years Part solid No routine follow-up: CT after 6–12 months: If unchanged and solid component remains <6mm: Annual CT for 5 years. Solid component ≥6mm: highly suspicious; Multiple nodules CT after 3–6 months.
