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]
Large, prominent subpleural bullae. Spontaneous pneumothorax often results from rupture of such lesions. Honeycomb fibrosis is present in the subpleural lung parenchyma. In emphysema the spaces resulting from alveolar wall destruction have thin, delicate walls without intervening fibrosis and resemble the appearance of a spider web.
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). The units making up the substructure of the lung (alveoli) become permanently enlarged due to the destruction of their walls.
David Lynch is 'homebound whether I like it or not' as he battles emphysema, a condition that affects breathing. But the filmmaker says he will 'never retire.' David Lynch has emphysema that ...
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.
In medicine, a bleb is a blister-like protrusion (often hemispherical) filled with serous fluid.Blebs can form in a number of tissues by different pathologies, including frostbite and can "appear and disappear within a short time interval".
