CTICasesChronic bronchiectasis from remote silo filler's disease
Imaging findings
CT scan of a 70-year-old retired farmer shows severe, upper- and mid-lung predominant bronchiectasis affecting the 4th-to-6th order bronchi (Williams-Campbell-like pattern) with mosaic attenuation/air trapping, and co-existing basilar-predominant pulmonary fibrosis.
Key takeaways
Silo filler's disease is an acute chemical pneumonitis caused by inhalation of nitrogen dioxide gas from silage. Severe exposure can lead to chronic airway injury, bronchiectasis, and constrictive bronchiolitis, which can coexist with other age-related fibrotic lung diseases.
