The meaning of right lower lung alveoli is the presence of a pathologic change called a pulmonary alveolus in the right lower lung found on a chest X-ray or CT of the lungs. A pulmonary blister is a structural change that refers to the destruction of the alveolar wall between two neighboring alveoli, which results in the fusion of the alveoli with each other to form a larger cystic cavity. Pulmonary alveoli can be either single or multiple. Lung blisters tend to be small in diameter and have a mild effect on the body, and can be asymptomatic, being detected only during a physical examination. However, huge lung blisters have the risk of rupture, especially those adjacent to the pleura. When lung blisters rupture, they can cause pneumothorax, resulting in chest tightness, shortness of breath, and difficulty in breathing, so huge lung blisters adjacent to the pleura can be surgically resected to relieve the risk of triggering pneumothorax. In addition, if the complication of pulmonary herpes causes cough, sputum, or even fever symptoms, appropriate anti-infection treatment is also needed.
