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 tomo graphy (HRCT) findings of pulmonary involvement in primary Sjogren's syndro me. The study included 60 patients who met the diagnostic criteria for prim ary 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%), f ollowed by subpleural small nodules (78%), non-septal linear opacity (75%), interlobular septal thickening (55%), bronchiectasis (38%), and cysts (30% ).
