Ground glass nodules in the anterior basal segment of the lower lobe of the right lung may be caused by lung tumors, inflammation, tuberculosis and other causes. Mulled glass nodule in the anterior basal segment of the right lower lobe of the lung is a chest CT manifestation, i.e., the anterior basal segment of the right lower lobe of the lung appears as a cloud-like rounded thin shadow with mildly increased density, and the bronchial and vascular texture within the nodule can still be shown. Generally, regular chest CT review is needed, and drug treatment or surgical resection is adopted. 1. Drug treatment: After anti-inflammatory or anti-tuberculosis treatment, some of the ground-glass nodules in the anterior basal segment of the lower lobe of the right lung caused by lung inflammation or tuberculosis can be reduced and absorbed after a short period of observation. 2. Surgical resection: Long-existing ground-glass nodules in the anterior basal segment of the lower lobe of the right lung have the possibility of malignant changes. If there is an increase in the diameter, density or shape during the review of chest CT, lung malignant tumors are not excluded, and surgical resection can be performed in combination with the specific circumstances. For patients with ground glass nodules in the anterior basal segment of the lower lobe of the right lung, it is recommended to go to the thoracic surgery outpatient clinic in a timely manner, so as to have their conditions clarified by a professional doctor and be given corresponding treatments.
