An Unusual and Rare Location of Intra-articular Rheumatoid Nodule in the Elbow Joint - A Case Report.

Rheumatoid nodules are the most common extra-articular manifestation of rheumatoid arthritis. Intra-articular rheumatoid nodules are very rare and usually associated with clinical symptoms. Case reports of intra-articular rheumatoid nodules in the knee joint, wrist joint, ankle joint, and sacrococcygeal joint are reported. However, an intra-articular rheumatoid nodule in the elbow joint has not been reported in the literature. Herein, we report a unique and rare case of a symptomatic intra-articular rheumatoid nodule in the elbow joint of a 49-year-old female with a 15-year history of rheumatoid arthritis. The symptoms resolved after surgical excision of the nodule.
