A non-metabolically active ground-glass nodule with partially visible calcification is likely to be an old lesion, a sign of local inflammation that has become mechanized.
If a ground glass nodule is not metabolically active, it is likely that localized calcification will occur at a later stage, with large amounts of calcium deposited in the nodular tissue, most often after the inflammation of the lung tissue has resolved.
In the absence of cough, sputum, or chest pain, no specific treatment is needed when partial calcification of an inactive ground-glass nodule is detected on imaging such as CT or magnetic resonance imaging.
Calcification of non-metabolically active ground-glass nodules indicates that the local lesion tissue is relatively stable, and the possibility of malignant changes in the later stage is also unlikely, usually need to pay attention to a light diet, but also need to be regularly reviewed, and if abnormal changes are found, it is necessary to consult a doctor in a timely manner.
