Bronchiectasis
Permanent airway dilation that can follow chronic infection or airway injury
Bronchiectasis is chronic widening and distortion of the airways that can predispose to mucus retention and recurrent infection.
Bronchiectasis means some airways have become abnormally widened and damaged. This can make it easier for mucus to collect and infections to recur.

What it is
- This is a chronic structural airway disorder characterized by irreversible bronchial dilation, often related to prior infection, inflammatory disease, immune problems, or obstruction
How it appears on chest X-ray
- On chest X-ray, bronchiectasis may appear as tram-track opacities, ring shadows, chronic peribronchial thickening, or lower-lung scarring, though CT shows it much better
What radiologists look for
- Radiologists look for chronic airway dilation, mucus impaction, associated scarring, recurrent infection patterns, and whether CT is needed for better characterization
How X-ray helps
- X-ray may suggest chronic airway disease, but CT is usually the key test for confirming and characterizing bronchiectasis
Common causes
- Causes include prior severe infection, cystic fibrosis, immune deficiency, aspiration, obstruction, allergic bronchopulmonary disease, and chronic inflammatory airway injury
Symptoms / associated symptoms
- Symptoms often include chronic productive cough, recurrent chest infections, sputum production, shortness of breath, and occasional hemoptysis
Risk factors
- Risk factors include recurrent infection, chronic lung disease, immune problems, aspiration risk, smoking-related damage, and selected inherited conditions
Why it can matter clinically
- Complications can include recurrent pneumonia, mucus plugging, chronic sputum production, hemoptysis, and progressive lung function loss
When to seek medical care
- Medical review is important for chronic productive cough, repeated chest infections, coughing blood, or worsening shortness of breath
Evaluation and diagnosis
- Evaluation often includes CT chest, sputum history, pulmonary function testing, infection review, and workup for underlying causes when appropriate
Treatment approaches
- Management may include airway clearance therapy, infection treatment, pulmonary follow-up, bronchodilator support in selected cases, and treatment of underlying disorders
Medication classes clinicians may use
Treatment often focuses on infection control, airway clearance, bronchodilation in selected cases, and management of underlying causes.
Treatment modalities commonly paired with medication decisions
- Airway clearance therapy
- Treatment of infection
- Pulmonary follow-up
- Cause-directed management
Bronchodilators
May be used when airflow obstruction or airway reactivity contributes to symptoms.
- albuterol
Antibiotics
Often used during infectious exacerbations or in selected chronic suppression plans.
- amoxicillin-clavulanate
- azithromycin in selected settings
FAQ
Can chest X-ray diagnose bronchiectasis?
It can suggest it, but CT is much better for confirming and mapping bronchiectatic airways.
Does bronchiectasis always come from infection?
No. Infection is one cause, but immune disorders, obstruction, aspiration, and inherited conditions can also contribute.
