Pulmonary involvement in primary Sjogren's syndrome - Spectrum of pulmonary abnormalities and computed tomography findings in 60 patients

The purpose of this study was to describe the high-resolution computed tomography (HRCT) findings of pulmonary involvement in primary Sjogren's syndrome. The study included 60 patients who met the diagnostic criteria for primary Sjogren's syndrome. The authors retrospectively reviewed the presence, extent, and distribution of various HRCT findings. Results showed that the most common HRCT findings were areas with ground-glass attenuation (92%), followed by subpleural small nodules (78%), non-septal linear opacity (75%), interlobular septal thickening (55%), bronchiectasis (38%), and cysts (30%).
