Pulmonary bullae is a new term for many people, and it is not easy to be associated with pneumonia, tuberculosis, emphysema, lung abscess and so on. In fact, these diseases are the pathogens of pulmonary vesicles, and some are idiopathic pulmonary vesicles. These alveolar pathogens seem to be unrelated diseases, but pathologically there are edema, stenosis, partial obstruction of the lumen and valvular effect after inflammation of the small bronchi.

Pulmonary vesicle

Therefore, these pathogens are easy to cause pulmonary vesicles, and the most likely cause of pulmonary vesicles is emphysema. Because of these primary bronchial lumen, that is, alveolar stenosis, partial obstruction and the formation of valve, when gas exchange, the air is easy to enter but not easy to discharge, and the retention will increase the pressure in the alveolar cavity. The inflammation damages the lung tissue, and the pressure in the alveoli is increasing, resulting in rupture of the alveolar wall and septum.

On the other hand, the ruptured alveoli will merge with each other, thus forming a larger balloon cavity, that is, pulmonary vesicles. Pulmonary vesicles caused by emphysema are also characterized by multiple vesicles and thin walls. If the pressure in the lung increases and the alveoli burst and form alveoli, part of the alveolar wall will be composed of the pleura and become the subpleural alveoli. There is also the formation of a string of small pulmonary vesicles at the edge of the lung lobe, also known as pulmonary vesicles, and often coexist with pulmonary vesicles, if ruptured again to form a pneumothorax, hemothorax and so on.

Acute pulmonary abscess caused by pulmonary bullae

People may think that concurrent or secondary pulmonary vesicles are easily acquired by adults, but in fact, infants and young children are also easy to get pulmonary vesicles, because children are prone to pneumonia, lung abscess, and tuberculosis. If the treatment is not timely, or if it is not cured completely, the probability of causing and complicating pulmonary vesicles may rise in a straight line, forming single or multiple pulmonary vesicles, most of which are caused by pulmonary tuberculosis.
