Pulmonary tuberculosis can produce ground glass nodules, which are mainly examined and diagnosed by imaging such as chest CT and X-rays. Tuberculosis is an aggressive infection caused by Mycobacterium tuberculosis, which can easily cause nodules in the lungs, as well as cavities, corn-like shadows, and calcified spots in patients. Glassy nodules produced by tuberculosis are difficult to remove, and they may calcify after the tuberculosis is cured, resulting in a large number of calcified spots. The ground glass nodule shadow may be caused by inflammation or malignant tumor in addition to tuberculosis, and regular chest CT review is required to determine its nature. If it is malignant, it should be surgically removed as early as possible to cure the lung cancer at an early stage.
