Pulmonary alveolus, or lung blister, is diagnosed mainly by chest x-ray or chest ct. It will not heal on its own without treatment.
Lung blisters are caused by various reasons to increase the pressure in the alveolar cavity, leading to the rupture of alveoli and fusion with each other to form an air-containing cystic cavity with a diameter of more than >1cm. Generally, a single pulmonary blister or a small number of pulmonary blisters are asymptomatic and are mainly diagnosed by chest X-ray or chest CT.
If the chest X-ray sees a thin circular cavity in the lung field, no or only sparse lung texture in the cavity, or only striated shadows, and discontinuous curved blister walls, then it can be diagnosed as pulmonary herpes. A pulmonary hernia is a round, translucent area with no lung texture on chest CT. Chest CT is more effective than X-ray in detecting small, single alveoli.
Since pulmonary bullae are structural changes in the lung tissue, they cannot be cured without treatment, and their treatment is mainly to slow down their progression by treating their primary diseases such as tuberculosis and chronic obstructive pulmonary disease. No treatment is required when asymptomatic, but surgery can be performed under the supervision of a physician if a pneumothorax is present or if the risk of rupture is high.
