High-resolution chest CT in systemic lupus erythematosus.

Abstract

The results of this study, the first to describe the HRCT findings in SLE, suggest that airways disease, lymphadenopathy, and interstitial lung disease are common thoracic manifestations of SLE, whereas pleural abnormalities are less common than previously suggested. HRCT evidence of airways disease and interstitial lung disease was frequently present despite an absence of symptoms, a normal chest radiograph, and normal pulmonary function testing. HRCT provides a sensitive and noninvasive technique for detecting pulmonary involvement in SLE, with the added advantage that it can be performed in all patients, including those too compromised to undergo a surgical procedure. In patients with advanced disease, HRCT permits procedures such as bronchoalveolar lavage and lung biopsy to be directed toward areas of particular interest.
