How serious is a ground-glass lung nodule?

The advent of CT screening for lung cancer has increased the incidence of ground-glass nodules (GGNs). GGNs, especially part-solid GGNs, are more likely to be lung cancer than solid nodules.

What are ground-glass nodules in lungs?

Ground-glass nodules (GGNs) on computed tomography (CT) are hazy lesions that do not obscure underlying bronchial structures or pulmonary vessels. GGNs are manifestations of both malignant and benign lesions, such as focal interstitial fibrosis, inflammation, or hemorrhage (1).

Can an infection cause ground-glass nodules?

In patients with immune deficiency not caused by AIDS, ground glass opacities are common but nonspecific, as they can be caused by viral or pyogenic infection [18].

Does ground-glass nodules mean cancer?

Abstract: Pulmonary nodules with ground-glass opacity (GGO) are frequently observed and will be increasingly detected. GGO can be observed in both benign and malignant conditions, including lung cancer and its preinvasive lesions.

What percent of ground-glass nodules are cancerous?

Regarding SSNs, including pure ground-glass nodules (pGGNs), named nonsolid nodules and part-solid nodules (PSNs), results derived from the ELCAP [14] and the following I-ELCAP screening studies [16, 17] demonstrated a prevalence of malignancy for small nodules of 0% (considering a maximum nodule diameter of 5 mm) and …

How do you treat ground-glass nodules?

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.

What percentage of ground-glass nodules are cancerous?

What percentage of ground glass nodules are cancerous?

Can ground glass in lungs go away?

Most clinicians have probably observed that a percentage of GGNs disappear spontaneously (a transient GGN). My research group found that 37% of pure GGNs (pGGNs) and 48% of mixed GGNs (mGGNs) regressed or disappeared within 3 months, which suggested their inflammatory nature (1).

How do you treat ground glass nodules?

Are ground glass opacities the same as nodules?

Ground glass opacifications (GGO) are a subset of pulmonary nodules or masses with non-uniformity and less density than solid nodules.
