What are the different types of collapsed lung?

There are five main types of collapsed lung:

• Primary spontaneous pneumothorax: Collapsed lung sometimes happens in people who don’t have other lung problems. It can occur due to abnormal air sacs in the lungs that break apart and release air.
• Secondary spontaneous pneumothorax: Several lung diseases may cause a collapsed lung. These include chronic obstructive pulmonary disease (COPD), cystic fibrosis and emphysema.
• Injury-related pneumothorax: Injury to the chest can cause collapsed lung. Some people experience a collapsed lung due to a fractured rib, a hard hit to the chest or a knife or gunshot wound.
• Latrogenic pneumothorax: After certain medical procedures such as lung biopsy or a central venous line insertion, some people can have complications that include a pneumothorax.
• Catamenial pneumothorax: This rare condition affects women who have endometriosis. Endometrial tissue lines the uterus. With endometriosis, it grows outside the uterus and attaches to an area inside the chest. The endometrial tissue forms cysts that bleed into the pleural space, causing the lung to collapse.
