How are pulmonary ground-glass nodules treated?

Ground-glass nodules (GGNs) are a radiological term used in chest CT imaging. They appear as hazy, faint, cloud-like opacities representing a slight increase in lung tissue density on CT scans. Their texture resembles frosted glass—hence the name “ground-glass nodule.” When GGNs are diffusely distributed throughout the lungs, they are typically attributable to inflammatory processes. However, when appearing as discrete ground-glass nodules, they may indicate malignant lesions. So, how are pulmonary ground-glass nodules treated? Below is an overview.

How Are Pulmonary Ground-Glass Nodules Treated?

1. Western Pharmacotherapy

For ground-glass nodules caused by pulmonary infectious diseases—such as tuberculosis, viral pneumonia, or bronchopneumonia—anti-tubercular agents or antibiotics (e.g., rifabutin, fluconazole, cefdinir) may be administered for anti-infective treatment. Additionally, adjunctive therapies—including antispasmodic and cough-suppressant agents, as well as bronchodilators—are often employed. Examples include ambroxol-terbutaline oral solution, bear-bile fritillary oral liquid, and ipratropium bromide inhalation solution.

2. Traditional Chinese Medicine (TCM)

TCM herbal formulas may also be used. For instance, Mahuang Xingshi Decoction (a combination of Ephedra, Semen Armeniacae Amarum, gypsum, Bupleurum, Scutellaria, Houttuynia, Isatis leaf, Rhizoma Polygonati, Rhizoma Paridis, earthworm, silkworm pupa, Artemisia annua, Polygonum cuspidatum, honeysuckle flower, wild chrysanthemum, and licorice) exerts effects of clearing heat, detoxifying, promoting lung function, and relieving wheezing. Patients should follow physician instructions to take one dose daily, decocted with an appropriate amount of water.

3. Surgical Intervention

The treatment strategy for pulmonary ground-glass nodules depends primarily on their size, location, and likelihood of malignancy. If a GGN lesion is relatively large and exhibits morphological features suggestive of malignancy, surgical resection via thoracoscopy is generally recommended at a thoracic surgery department. Conversely, if the nodule is small (<5 mm) and deemed benign, no specific intervention is required; instead, regular follow-up surveillance is advised.
