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.
The differential diagnosis for ground-glass opacities is broad. General etiologies include infections, interstitial lung diseases, pulmonary edema, pulmonary hemorrhage, and neoplasm.
Minor opacity of cornea, unspecified eye. H17.819 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM H17.819 became effective on October 1, 2018.
An abscess is also noted in the right lung (screen left). There are seven general patterns of ground-glass opacities. When combined with a patient's clinical signs and symptoms, the GGO pattern seen on imaging is useful in narrowing the differential diagnosis.

Summary. Ground glass opacity (GGO) refers to the hazy gray areas that can show up in CT scans or X-rays of the lungs. These gray areas indicate increased density inside the lungs. The term comes from a technique in glassmaking during which the surface of the glass is blasted by sand. This technique gives the glass a hazy white or frosted ...
Diffuse: Diffuse opacities show up in multiple lobes of one or both lungs. This pattern occurs when the air in the lungs is replaced with fluid, inflammation, or damaged tissue. Nodular: This type can indicate both benign and malignant conditions.
Lobules are the hexagonal divisions of the lung. The connective tissue between the lobules is unaffected. Mosaic: This pattern develops when small arteries or airways within the lung are blocked. The opaque areas vary in intensity. Crazy paving: Crazy paving shows up as a linear pattern.
in 54 participants found that GGO most commonly showed up in the lower lobes of the lungs as round opacities, but that as the disease progressed, it became more patchy and affected all lobes. The symptoms of COVID-19 can include any of the following. Trusted Source.
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. When a substance other than air fills an area of the lung it increases that area's density. On both x-ray and CT, this appears more grey or hazy as opposed to the normally dark-appearing lungs. Although it can sometimes be seen in normal lungs, common pathologic causes include infections, interstitial lung disease, and pulmonary edema.
There are seven general patterns of ground-glass opacities. When combined with a patient's clinical signs and symptoms, the GGO pattern seen on imaging is useful in narrowing the differential diagnosis. It is important to note that while some disease processes present as only one pattern, many can present with a mixture of GGO patterns.
Centrilobular GGOs refer to opacities occurring within one or multiple secondary lobules of the lung, which consist of a respiratory bronchiole, small pulmonary artery, and the surrounding tissue. A defining feature of these GGOs is the lack of involvement of the interlobular septum. Potential causes of centrilobular GGOs include pulmonary calcifications from metastatic disease, some types of idiopathic interstitial pneumonias, hypersensitivity pneumonitis, aspiration pneumonitis, cholesterol granulomas, and pulmonary capillary hemangiomastosis.
General etiologies include infections, interstitial lung diseases, pulmonary edema, pulmonary hemorrhage, and neoplasm. A correlation of imaging with a patient's clinical features is useful in narrowing the diagnosis. GGOs can be seen in normal lungs.
Sarcoidosis is an additional cause of a mosaic GGOs due to the formation of granulomas in interstitial areas. This may coexist with granulomatosis with polyangiitis, leading to diffuse areas of increased attenuation with ground-glass appearance.
The first usage of "ground-glass opacity" by a major radiological society occurred in a 1984 publication of the American Journal of Roentgenology. It was published as part of a glossary of recommended nomenclature from the Fleischner Society, a group of thoracic imaging radiologists.
It is important to note that while many of the pulmonary infections listed below may lead to GGOs, this does not occur in every case.
