Whether a pulmonary ground-glass nodule of up to 10 mm will disappear on its own needs to be seen in the context of the nature of the nodule. A pulmonary ground glass nodule is a lesion found on a thin layer CT scan of the lungs and is categorized as a pure ground glass nodule or a mixed ground glass nodule. In general, CT shows glassy nodules are common in inflammatory diseases and some early lung cancers. If the ground glass nodules are due to focal fibrosis, focal edema or focal hemorrhage, they are benign lesions and may disappear during observation and review. If the ground-glass nodule does not disappear during observation, CT is recommended at 6-12 months to determine stability, and if there is no increase in the size of the nodule, CT can be performed every 2 years until 5 years. If the ground-glass nodule is a partially solid pulmonary nodule ≥6 mm, repeat thin-layer chest CT around the 3rd-6th month after detection, and consider biopsy/surgery if the nodule increases in size; if the nodule decreases in size, regular yearly follow-up screening is recommended, with follow-up in non-high-risk individuals according to the specialist’s medical advice. If the nodule remains unchanged, regular follow-up screening is recommended, with follow-up according to the specialist’s instructions.
