Bronchiectasis evaluation 2025: pediatric and adult perspectives

Area of Science:

• Pulmonology
• Radiology
• Pediatric Medicine

Background:

• Bronchiectasis is characterized by bronchial dilation due to chronic infection and inflammation.
• Diagnosis involves clinical suspicion of suppurative lung disease and confirmation via computed tomography (CT) imaging.
• Etiologies range from inherited conditions like cystic fibrosis to secondary causes such as infections and immunodeficiency, with up to 40% remaining idiopathic.

Purpose of the Study:

• To review age-specific considerations in the diagnostic evaluation of bronchiectasis.
• To address unique aspects of pediatric bronchiectasis diagnosis compared to adults.

Main Methods:

• Review of current literature on bronchiectasis diagnosis.
• Focus on differentiating adult and pediatric diagnostic pathways.
• Emphasis on computed tomography (CT) imaging findings.

Main Results:

• Bronchiectasis is defined by radiographic evidence of bronchial dilation, commonly identified when bronchial diameter exceeds that of adjacent blood vessels on CT scans.
• Clinical presentation includes persistent cough with sputum and recurrent respiratory infections.
• A broad differential diagnosis is essential, with subsequent testing tailored to patient-specific suspected etiologies.

Conclusions:

• Bronchiectasis evaluation requires a broad initial differential diagnosis, followed by focused testing for specific etiologies.
• A combination of diagnostic tests is often necessary to determine the cause.
• Longitudinal monitoring, including respiratory cultures, lung function tests, and repeat CT imaging, is vital for managing patients with bronchiectasis.
