摘要
rheumatoid nodules are the most common extra-articular manifestation of rheumatoid arthritis and are present in around 20-25% of patients. their etiology is unknown and although the nodules may undergo spontaneous remission during the treatment of rheumatoid arthritis, they usually constitute a therapeutic challenge. the present paper describes a case in which the response of rheumatoid nodules was evaluated by ultrasound following infiltration of triamcinolone acetonide and 5-fluorouracil.
