CTICasesSjögren's-Associated Lymphocytic Interstitial Pneumonia
Imaging findings
Chest CT shows multiple poorly defined centrilobular nodules, branching opacities, and small cystic spaces in a patient with Sjögren's syndrome. Pathological biopsy confirmed lymphocytic interstitial pneumonia (LIP).
Key takeaways
LIP is a lymphoproliferative disorder strongly associated with autoimmune diseases like Sjögren's syndrome. It typically manifests as centrilobular nodules, ground-glass opacities, and characteristic thin-walled cysts.
