Imaging findings
Long-term progression from peri-bronchovascular ground-glass opacities and nodules to significant bronchiectasis over a 10-year period.

Airway abnormalities in GPA may be secondary to chronic necrotizing inflammation centered on vasculature, leading to permanent structural damage like bronchiectasis.
