When the subpleural bullae are significant, the emphysema is called bullous emphysema. Bullae can become extensive and combine to form giant bullae. These can be large enough to take up a third of a hemithorax, compress the lung parenchyma, and cause displacement. The emphysema is now termed giant bullous emphysema, more commonly called ...
A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness. [1] A bleb has a wall thickness of less than 1 mm. [2] By radiology definition, it is up to 1 cm in total size. [3]
Low magnification micrograph of pneumatosis intestinalis in bowel wall.. Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity.The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
Bullectomy is a surgical procedure in which dilated air-spaces or bullae in lung parenchyma are removed. [1] Common causes of dilated air-spaces include chronic obstructive pulmonary disease and emphysema. Patients with giant bullae filling half the thoracic volume and compressing relatively normal adjacent parenchyma are recommended for ...
An axial CT image showing bullous emphysema of the lungs. There are larger air pockets on the right than left. Bullous emphysema is a condition seen in patients with chronic obstructive pulmonary disease (COPD).

David Lynch revealed in a new interview that he was diagnosed with emphysema and can no longer “leave the house” due to fears of getting COVID. “I’ve gotten emphysema from smoking for so ...
Historically, tuberculosis was the most common cause of the lung cavity (and still is in areas where tuberculosis is endemic); [7] however, the cavity can also be caused by sarcoidosis, bullae, bronchiectasis, or cystic lung disease. [2] Chronic necrotizing aspergillosis and invasive aspergillosis are usually seen in immunocompromised people. [4]
