Abstract

Geodes are noted frequently in rheumatoid arthritis (RA), but large geodes of the femur are uncommon. We describe a patient with RA and a large geode in his femur; histological findings were consistent with a rheumatoid nodule and chronically inflamed synovium. We review the literature of large femoral geodes and what this particular manifestation may reflect about the pathogenesis of RA.
