To describe the high-resolution CT (HRCT) findings of the lung in patients with rheumatoid arthritis(RA). We retrospectively reviewed high-resolution CT scans of 38 patients who complained of dyspnea(n=9) and who had abnormalities on chest radiography (n=29) including 2 patients with Caplan's syndrome among 2436 patients of whom fulfilled the revised criteria of american rheumatism association for RA. Open lung biopsy was done in 3 patients. Among the totoal of 2436 patients with RA, abnormal findings were found in 29 patients (1.2%) on chest radiography and in 35 patients (1.4%) on chest HRCT. The HRCT scans showing the following abnormalities : ground-glass opacity (60.5%), thickening of interlobular septae (55.3%), intralobular lines (55.3%), small nodules (44.7%). honeycombing (42.1%), emphysema (31.6%), bronchiectasis(28.9%), mediastinal lymphadenopathy(26.3%), bronchiolitis obliterans (15.8%), pleural thickening (15.8%), consolidation (15.8%), pericardial effusion (5.3%) and pericardial thickening (5.3%). In patients with rheumatoid arthritis, HRCT scans of the lung commonly show areas of ground-glass opacity, thickening of interlobular septae, intralobular lines, small nodules, honeycombing, emphysema, bronchiectasis. And the presence and the extent of the lung lesions could recognize in detail by using HRCT.
