Pulmonary Bulla

Pulmonary bulla is a thin-walled airspace >1 cm within lung, usually subpleural, associated with emphysema/smoking, often asymptomatic but may cause dyspnea or rupture into pneumothorax. Treatment: observe if small/asymptomatic; smoking cessation; treat underlying emphysema (bronchodilators/rehab); surgical resection if giant compressive/recurrent pneumothorax; chest tube for pneumothorax; bullectomy; monitor.

Common Symptoms

Usually asymptomatic; dyspnea if giant; may rupture causing pneumothorax

Causes and Pathogenesis

Alveolar wall destruction forms thin-walled airspace, often in emphysema.

Treatment

Observe; treat underlying emphysema; surgery if giant/recurrent pneumothorax

Preventive Measures

Smoking cessation; treat emphysema.
