CTICasesFibrotic Hypersensitivity Pneumonitis
Imaging findings
Fibrosing lung disease with reticulation and architectural distortion, but lacking classic UIP findings like sub-pleural honeycombing.
Key takeaways
Surgical biopsy revealed airway-centric fibrosis and loose granulomas, leading to a diagnosis of fibrotic hypersensitivity pneumonitis. Management of such cases involves distinguishing progressive phenotypes and identifying potential environmental exposures before escalating to anti-fibrotic therapy.
