Chest CT findings were qualitatively and semiquantitatively analyzed with comparison between 1-SS and 2-SS, and correlation with anti-SSB\/La seropositivity and the presence of clonally derived lymphoproliferative disorder (cLPD), which are known to be pathognomonic and prognostic clinical features of SS patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>All patients were women with median age of 60 years. Anti-SSB\/La antibodies were found in 17 primary SS patients and 4 2-SS patients. Eleven patients with cLPD were identified and all of them had 1-SS. The most frequent CT finding in both types of patients was interlobular septal thickening. Secondary SS was associated with a significantly greater frequency and extent of honeycombing versus 1-SS. Univariate and multivariate analysis showed a significant association between honeycombing and 2-SS. In patients with 1-SS and in the SS group as a whole, we observed independent and significant associations between cysts and anti-SSB\/La seropositivity or cLPD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>Cysts are significantly associated with anti-SSB\/La seropositivity and cLPD.
