Imaging findings
High-resolution CT shows hyperinflated lungs with widespread centrilobular nodules, tree-in-bud opacities, bronchocentric nodularity, and bronchiectasis. These findings are most severe within the right middle lobe and lingula.
Key takeaways
Diffuse panbronchiolitis is a chronic, progressive inflammatory airway disease that primarily affects the respiratory bronchioles. While classically described in East Asian populations, it can be encountered in non-Asian patients and is characterized by a strong association with chronic sinusitis and a dramatic therapeutic response to long-term, low-dose macrolide therapy.
