CTICasesSegmental airway granulomatosis with polyangiitis (GPA)
Imaging findings
CT scan shows marked wall thickening and luminal narrowing predominantly affecting the segmental and subsegmental bronchi of all lobes, sparing the trachea and main bronchi.
Key takeaways
Granulomatosis with polyangiitis (GPA) can manifest as isolated or predominant segmental airway narrowing and wall thickening, which may simulate other inflammatory or congenital airway diseases.
