Imaging findings
Chest CT shows peripheral-sparing (central/peribronchovascular-predominant) NSIP-like reticulation and lung fibrosis, associated with extensive lobular air trapping and mosaic attenuation. The patient had bird exposure (Sun Conure).
Key takeaways
Chronic hypersensitivity pneumonitis (HP) can mimic NSIP but is frequently characterized by the presence of lobular air trapping (three-density sign or mosaic attenuation) and a history of antigen exposure (e.g., avian proteins).
