In a patient with Sjogren and these findings, what malignancy should you consider in your differential diagnosis?


MALT lymphoma

MALT lymphoma in a 60-year-old woman with primary Sjögren syndrome. (a) High-resolution CT image shows hazy area of increased attenuation in the lung with preservation of vascular markings (indicated by ground-glass attenuation), a finding that represents either infiltration by lymphoplasmacytes or fibrous change in the alveolar septa. Interlobular septal thickening and intralobular reticular areas of attenuation (arrowheads) correspond to lymphocytic infiltration and mild fibrosis of inter- or intralobular septa.


Name the finding


Multilocular thymic cyst

Multilocular thymic cyst in a 43-year-old woman with primary Sjögren syndrome. (a) Contrast-enhanced CT image obtained with mediastinal window settings shows a multilocular cystic mass in the anterior mediastinal compartment. Although the cystic walls demonstrate focal thickening (arrows), no solid component is seen.
