[Pulmonary infiltrations in Sjögren syndrome--a radiodiagnostic study].

We report on the radiological findings of 8 female patients with primary Sjögren's syndrome and pulmonary infiltrations. In the chest x-ray, all patients featured an interstitial diffuse bilateral reticular pattern which was most prominent in the bases. The apices of the upper lobes were not involved. There were no pleural effusions. The radiologic appearances changed only slowly. In three cases the lesions progressed to form a patchy confluent pattern. 4 of 8 patients developed within 24 months a nodal or extranodal lymphoma of low-grade malignancy.
