Subsolid pulmonary nodules, also known as ground-glass or ground-glass nodules, can be detected clinically by imaging such as CT. The malignancy of this nodule is present, especially in nodules with more than 10 nodules in both lungs, and may have accompanying symptoms, especially when caused by metastases of malignant tumors outside the lungs, as well as by infections within the lungs, which can manifest as subsolid lung nodules. Clinically, for the treatment of the etiology, if the patient develops lung cancer or other parts of the cancer, radiotherapy, chemotherapy, interventional therapy and biological therapy should be performed for the malignant tumor so that its condition can be controlled. Early stage lung cancer can be removed by surgery. For subsolid lung nodules, chest CT should be performed within six months for review to determine the growth rate and to judge the change of their condition.
