Ground Glass Opacities
Mar 30, · 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 . Apr 17, · According to Isabel Oliva Cortopassi, MD, chief of thoracic imaging at Yale Medicine and an associate professor of radiology and biomedical imaging, ground glass opacities (GGOs, for short).
How to beat the rng ground glass lung result from a CT scan is a non-specific finding that describes an area characterized by a small increase in lung density, explains the National Institutes of Health.
Patients with early diffuse pulmonary infiltrative diseases are more likely to present with an area of ground glass opacity in the lung. Although a lung may have an opaque area described as having a ground-glass appearance on the CT scan, the bronchial walls and vascular structures of the lung remain visible, according to the NIH. This type of pulmonary opacity may be diffuse or patchy and is a significant finding because it may represent an abnormality that is active and treatable.
There can be numerous causes of a ground glass lung condition such as sarcoidosis or pulmonary fibrosis, note the NIH. A ground glass lung opacity may also be observed in conditions such as alveolar proteinosis, desquamative pneumonitis, hypersensitive pneumonitis and drug-induced or radiation-induced lung disease.
If an area of ground glass opacity persists in the lung, it is usually classified as an adenocarcinoma, a classification that ranges from premalignant lesions to invasive disease, explains the Mayo Clinic. Lesions are generally slow growing, but because their significance is unknown, optimal management and follow-up procedures are not clearly understood.
As ofground glass lung opacities are an area of intensive research to better understand their significance and health risks. More From Reference. What Are the Different Departments of a Bank?
Aug 04, · A ground glass lung result from a CT scan is a non-specific finding that describes an area characterized by a small increase in lung density, explains the National Institutes of Health. Patients with early diffuse pulmonary infiltrative diseases are more likely to present with an area of ground glass opacity in the lung. Jul 05, · “A nodule in the lung can be from infection, irritation, or inflammation. It can be from other diseases, unrelated to cancer at all.” Hales notes that a ground glass opacity is a radiologist's characterization of how something may look on the scan. “It’s almost as if /5(24). Jul 29, · Ground glass opacities is basically a radiological finding of hazy opacity on your lung in CT scans. They indicate several health related conditions either acute or chronic. New Health Advisor.
The coronavirus pandemic has filled our vocabularies with more medical terms than most of us would ever hear about otherwise: flattening the curve , active and passive immunity , PPE. Another—ground glass opacities, referring to findings on computed tomography CT scans of COVID patients —has also been in the news lately, with reports showing that those specific findings on patient's scans can help diagnose and monitor coronavirus infections.
While it's important to note that ground glass opacities aren't specific to COVID, meaning they can show up in other conditions and infections, they are common among those with coronavirus. Here's what you need to know. According to Isabel Oliva Cortopassi, MD , chief of thoracic imaging at Yale Medicine and an associate professor of radiology and biomedical imaging, ground glass opacities GGOs, for short indicate abnormalities in the lungs.
Those lighter patches don't completely obscure the other structures in the lungs, says Jennifer Possick, MD , a Yale Medicine pulmonologist—that makes them different from lesions associated with lung cancer , which can often appear as solid. With GGOs, "there is haziness seen overlying an area of the lung, but the underlying structures of the lung airways, blood vessels, lung tissue can still be identified," she says. It resembles, well, ground glass, or glass that is still transparent but has a matte finish.
Experts Explain the Coronavirus Symptom. GGOs in chest CT scans can also indicate congestive heart failure , inflammatory interstitial lung diseases, and diffuse alveolar hemorrhage bleeding into the airspaces of the lungs , among other issues.
But one of the most common diagnosis for GGOs is viral pneumonias, most often caused by respiratory syncytial virus RSV , cytomegalovirus, herpes simplex virus, and coronavirus. Those findings, according to the researchers, show that "in the context of a travel history or exposure, the presence of nodular and peripheral ground glass opacities should alert the radiologists to [the possibility]" of a COVID diagnosis.
Doctors Explain This Coronavirus Symptom. Cortopassi points out that there are additional imaging appearances that can signal it as well—including consolidation a white portion on a lung CT that signifies fluid is present and septal thickening a thickening of the connective tissues within the lung, also indicative of fluid, fibrous tissue, or cell infiltration. These terms are important to know, especially if the words "ground glass opacities" ever come out of your doctor's mouth.
But Dr. Corotpassi reiterates that a COVID diagnosis doesn't automatically lead to a worsened condition in which these GGOs will show up in a CT scan, nor does an abnormal scan definitively mean a coronavirus infection. As always, however, if you are experiencing symptoms of COVID— dry cough , fever, shortness of breath , fatigue—it's best to call your doctor or other health care professional for a telemedicine evaluation don't go directly to the ER or your doctor's office, otherwise you risk infecting others or yourself.
Your doctor can then determine whether you should be tested for COVID and can help you figure out next steps on your way to a possible diagnosis. The information in this story is accurate as of press time. However, as the situation surrounding COVID continues to evolve, it's possible that some data have changed since publication.
