A well-defined ground-glass nodule represents a benign hyperplasia, while a blurred ground-glass nodule represents the possibility of malignant lesions.
Fuzzy and clear boundaries of ground-glass nodules are the imaging findings of high-resolution CT of the chest, which is a test that provides doctors with information about the size and shape of lung nodules and their relationship with the surrounding tissues.
Most of the clear border indicates benign hyperplasia, generally considered to be caused by inflammation, usually manifested as cough, sputum and other symptoms, patients do not need to worry too much, you can first go to the hospital for routine blood tests in order to dynamically follow up the imaging examination, in general, antibiotics can be applied to anti-infection treatment, and need to be regularly rechecked.
Ground-glass nodules with blurred borders represent the possibility of malignant lesions in the lungs, and patients need to go to the hospital in a timely manner and under the guidance of a professional doctor to conduct a pathological tissue biopsy, in order to determine whether or not it is a malignant nodule. Once the diagnosis is confirmed, the doctor will need to adopt surgery, radiotherapy and chemotherapy to treat the disease.
