Pulmonary manifestations of rheumatoid arthritis

Abstract

Rheumatoid arthritis (RA) is the most common of the classic connective tissue diseases. Its manifestations in the chest are varied as the pleura, lung parenchyma, airways, and pulmonary vasculature can all be involved. The approach to a patient with RA and respiratory complaints, radiographic findings, or physiologic abnormalities requires a broad understanding of these manifestations. Moreover, the potential for therapy-related toxicity adds further complexity to the pulmonary evaluation of these patients.
