When a bleb ruptures the air escapes into the chest cavity causing a pneumothorax (air between the lung and chest cavity) which can result in a collapsed lung. If blebs become larger or come together to form a larger cyst, they are called bulla.
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".
The potential benefits to family—whether pneumothorax has occurred in other family members or not—are no less significant. Identification of a pathogenic genetic variant in the index case enables testing, counseling, and surveillance/prophylaxis in family members carrying the same variant.

Pulmonary Blebs are small thin walled air blisters that develop in the lungs. When a bleb ruptures the air escapes into the chest cavity causing a pneumothorax (air between the lung and chest cavity) which can result in a collapsed lung.

Men are far more likely than women to develop blebs and bullaeby a margin of approximately 70% to 30%. Likewise, there are certain high-risk occupations that could increase your risk of developing lung blebs, such as those that put you in close contact with dust, chemicals, fibers, germs, or smoke among other things. Blebs and bullae are thought to...
Researchers suspect that tobacco and cannabis smoking, emphysema (also called Chronic obstructive pulmonary disease, or COPD), and other lung conditions can lead to the development of blebs and bullae. That’s because blebs are especially prevalent in damaged lung tissue. Emphysema is a type of COPD characterized by damage to the lung alveoli (air s...
Pulmonary blebs tend to appear in the upper lobes of the lung. When they rupture, the air held in the bleb escapes into the chest cavity, leading to a collapsed lung, also known as pneumothorax. Depending on the degree of collapse and a patient’s overall respiratory status, symptoms can include shortness of breath, difficulty breathing, and chest o...
The symptoms of a collapsed lung may be mild or severe and include: 1. Shortness of breath 2. Chest pain, which could be stronger on one side or the other 3. Sharp pain when you inhale 4. Lung pressure that increases with time 5. Lips or skin turning blue 6. Increased heart rate 7. Rapid breathing In most pneumothorax cases, a chest X-ray is the fi...
There are several pneumothorax treatment options, which may be a relief to hear. However, part of the reason for that is some treatments are debated in the medical community. For instance, while oxygen has been the traditional treatment for small, asymptomatic, or mildly symptomatic pneumothorax, recent medical literature has questionedits effectiv...
Diagnostic imaging, such as a CT scan that reveals blebs or bullae, is also a predictor for surgical intervention, since the recurrence risk is progressively higher in patients who have had a previous occurrence of bleb ruptures or pneumothorax. Low-dose computed tomography(LDCT) is the only recommended CT scan for people who are high-risk for lung...
Oct 3, 2016 · Blebs are cellular protrusions that have been shown to be instrumental for cell migration in development and disease. Bleb expansion is driven by hydrostatic pressure generated in the cytoplasm by the contractile actomyosin cortex.
