류마티스관절염 양상으로 발현된 말초 골결핵 1예

Abstract

A 30 year-old female visited our out-patient clinic with painful joint swelling in both hands and feet. Because she had testedpositive for rheumatoid factor, and her inflammatory markers were elevated, the case was initially classified as rheumatoid arthritis(RA), according to the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR)classification criteria. However, radiographic examinations, including simple radiography and MRI, revealed that her peripheralbone lesions were compatible with bone tuberculosis. The patient also exhibited pulmonary tuberculosis (TB) on chest X-ray andCT examinations. She was treated with isoniazid (INH), rifampicin (RFP), ethambutol (EMB), and pyrazinamide (PZA), andexhibited a good response to these medications. The patient was diagnosed as having bone TB, and her peripheral bone lesions wereresolved using anti-TB treatment. This was an uncommon case of bone TB mimicking RA.
