CTICasesSjögren's Syndrome-associated Cystic Lung Disease and Rheumatoid Rounded Atelectasis

Imaging findings
Chest radiography and CT show chronic, bilateral pleural thickening with rounded atelectasis, along with multiple new small, thin-walled cystic lesions in the right lower lobe.
Key takeaways
Chronic pleural thickening and rounded atelectasis can be secondary to systemic autoimmune diseases like rheumatoid arthritis. The development of small lung cysts in this clinical context should prompt consideration of secondary Sjögren's syndrome, where light chain or lymphoid interstitial pneumonia (LIP) deposition can lead to cystic lung parenchymal changes.
