What are bullae in the lungs?

Pulmonary bullae (singular: bulla) are focal regions of emphysema with no discernible wall which measure more than 1 or 2 cm in diameter 1-2. Some use the term pulmonary bleb for a similar lesion less than 1 or 2 cm, whereas others use both the terms bleb and bulla interchangeably.

Why do bullae form?

When alveoli are damaged, they form larger spaces called bullae that simply take up space. Bullae can't absorb oxygen and transfer it into your blood. Bullae often result from chronic obstructive pulmonary disease (COPD).

Is bullae life threatening?

Bullous pemphigoid usually goes away within 5 years, and generally responds well to treatment. However, blisters that rupture and become infected can lead to a life-threatening condition called sepsis. For this reason, it is important to seek treatment at your first sign of symptoms.

What causes bullae in COPD?

The two most common causes of bullous emphysema are smoking and alpha-1 antitrypsin deficiency (A1AD or AATD), an inherited autosomal codominant genetic condition.

Can bullae go away?

Bullae are typically easy to treat. They will resolve on their own without treatment if not due to an illness or skin condition. However, in some cases complications are possible. If open or drained, bullae have the potential to become infected.

Can lung bullae heal?

A bullectomy is a minimally invasive surgical procedure in which a surgeon removes one or more enlarged air sacs from the lung. There are few risks, and recovery is generally good. Following the procedure, a person should expect several weeks of recovery time before returning to normal activities. Giant bullae.

Are bullae cancerous?

Bullous disease of the lung and pneumothorax are both frequent conditions in thoracic surgery. Lung cancer may develop in patients with bullous emphysema,1,2 lung cysts3 and pneumothorax,4 which are usually treated as benign diseases; however, pulmonary carcinoma associated with bullous emphysema is unusual.

How long do bullae last?

Bullous pemphigoid often goes away on its own in a few months, but may take as many as five years to resolve. Treatment usually helps heal the blisters and ease any itching.

How do you treat lung bullae?

A bullectomy is a surgical procedure that involves removing bullae, which are enlarged, damaged air sacs in the lungs. A surgeon will remove one or more bullae through small incisions in the chest.

Do bullae in lungs go away?

Bullous lung disease is characterized by the development of bullae within the lung parenchyma. A bulla is a permanent, air-filled space within the lung parenchyma that is at least 1 cm in size and has a thin or poorly defined wall; it is bordered only by remnants of alveolar septae and/or pleura.

Are lung bullae common?

Thick-walled airspaces within the lung parenchyma or the presence of an air-fluid level within the cavity should prompt consideration of cavitating infection or malignancy with central necrosis. Although bullae may rarely become secondarily infected, infected bullae are far less common than lung abscesses.
