CTICasesSjögren's Syndrome with Hypersensitivity Pneumonitis Features
Imaging findings
Widespread ground-glass opacities, reticulation, mosaic attenuation, and thin-walled cysts.
Key takeaways
While cystic lung disease is associated with Sjögren's (often due to light chain deposition), the presence of mosaic attenuation/air trapping should also raise suspicion for chronic hypersensitivity pneumonitis (HP).
