CTICasesLight-Chain Deposition Disease
Imaging findings
Chest CT shows multiple discrete pulmonary cysts, some associated with vascular structures, in a patient with Sjögren's syndrome and light-chain deposition disease (LCDD).
Key takeaways
Light-chain deposition disease (LCDD) associated with Sjögren's syndrome can present with diffuse cystic lung disease. The cysts are thought to result from light-chain deposition in bronchial walls leading to small airway dilatation.
