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 ...
Oct 29, 2021 · Ground-glass opacities (GGO) are gray areas that computed tomography scans or X-rays of the lungs pick up. The normal lungs appear black in such scans. GGOs can be seen mostly in patients with moderate to severe respiratory conditions, such as infections, cancers, and inflammation. Recently, ground-glass opacities were seen in most patients infected with …
Sep 03, 2013 · Introduction. Ground-glass opacity (GGO) is a radiological finding in computed tomography (CT) consisting of a hazy opacity that does not obscure the underlying bronchial structures or pulmonary vessels ().Pure GGOs are those with no solid components, whereas part-solid GGOs contain both GGO and a solid component.
Apr 26, 2021 · Ground-glass opacity (GGO) is a non-specific term defined by the Fleischner society as the presence on high-resolution computed tomography (HRCT) of a hazy increase in lung density, not associated with obscuration of the underlying vessels or bronchial walls; if vessels are obscured, the term “consolidation” is preferred . GGO reflects the presence of a …
The current main treatment methods for pulmonary multifocal GGO are forming a troika including the following: surgery, stereotactic body radiation therapy (SBRT), and thermal tumor ablation (including radiofrequency ablation, microwave ablation, and cryoablation).

The doubling time for most malignant nodules is between 30 and 400 days. The absence of growth of solid nodule over at least a 2-year period is generally considered to be a reliable indicator of benignity.Aug 21, 2015
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.Mar 29, 2021
Ground-glass opacity (GGO) is a common finding on high resolution CT, characterised by areas of hazy increased attenuation of the lung with preservation of bronchial and vascular margins; it is not to be confused with consolidation, in which bronchovascular structures are obscured.
Clinically, low-malignant nodules can be treated with conservative treatment of regular CT follow-up. If the nodules are increased in size or solid component, more invasive therapy is suggested. Infections, benign nodules, and intrapulmonary lymph nodes often resolve or become stationary after regular follow-up.
GGNs are manifestations of both malignant and benign lesions, such as focal interstitial fibrosis, inflammation, or hemorrhage (1). However, slowly growing or stable GGNs are early lung cancers or their preinvasive lesions, atypical adenomatous hyperplasia (AAH) or adenocarcinoma in situ (AIS).Jul 4, 2018
Characteristic Clinical Features. Acute ground-glass opacities due to infection are seen most commonly in immunocompromised patients, who usually present with fever and progressive shortness of breath. Patients with diffuse pulmonary hemorrhage usually present with hemoptysis.
Chest CT in COVID-19 pneumonia demonstrates bilateral, peripheral, and basal predominant ground-glass opacities (GGOs) and/or consolidation in nearly 85% of patients with superimposed irregular lines and interfaces; the imaging findings peak 9–13 days after infection (7,8) (Fig 1).Jul 7, 2020
Causes of pulmonary opacity Lymphangitic metastasis, sarcoidosis, eosinophilic granuloma, collagen vascular diseases, inhalation injuries, idiopathic pulmonary fibrosis (“fibrosing alveolitis”), resolving pneumonia.
The combination of chest imaging showing predominantly upper lobe peripheral or subpleural patchy ground-glass opacities in a patient with a history of asthma along with peripheral and BAL eosinophilia is highly suggestive of CEP.Jun 19, 2016
The opacification is caused by fluid or solid material within the airways that causes a difference in the relative attenuation of the lung: transudate, e.g. pulmonary edema secondary to heart failure. pus, e.g. bacterial pneumonia. blood, e.g. pulmonary hemorrhage.Oct 30, 2021
