Small air sacs in the lower lobe of the right lung refers to cavity-like changes in the lower lobe of the right lung, which are caused by the expansion of the lung cavities, and are commonly seen in emphysema, pemphigus, and pulmonary cysts.
1. Emphysema: because of poor lung function, resulting in increased gas content in the alveoli due to increased residual gas in the lungs, small air sacs changes can be manifested.
2. Pulmonary pustules: due to congenital or acquired diseases, the alveoli fuse with each other and form cystic pustules, if small, usually do not affect the respiratory function of the lungs.
3. Pulmonary cysts: generally formed during the development of alveoli, manifested as cystic changes.
Small air sacs in the lower lobe of the right lung should go to a regular hospital, and the doctor will determine the specific cause of the disease according to the symptoms, signs and auxiliary examinations, and give the correct treatment for the cause of the disease.
