CTICasesAirway-Centered Fibrosis
Imaging findings
Ill-defined reticular and ground-glass opacities, lack of subpleural traction bronchiectasis or honeycombing. Pathology shows airway-centered fibrosis and peribronchiolar metaplasia.
Key takeaways
This pattern is suggestive of fibrotic hypersensitivity pneumonitis. The case highlights the utility of pathology in classifying fibrosis patterns that are otherwise indeterminate on CT.
