Abstract
INTRODUCTION: Tuberculous (TB) synovitis is a rare, treatable, potentially lethal form of extrapulmonary TB resulting from massive lymphohematogenous dissemination of Mycobacterium tuberculosis (M. tuberculosis). We presented a case of TB synovitis of the knee in a Caucasian HIV-negative man from Romania, a high TB incidence country. CASE REPORT: A 65-year old man presented with cough, high fever, mild wheezing, and swelling of the left knee. Chest radiography was normal. Sputum smears were Acid Fast Bacilli negative and Lowenstein-Jensen (L-J) culture negative for M. tuberculosis. Tuberculin skin test was negative. Respiratory symptoms disappeared in a week under antibiotics. Positive L-J cultures of knee punctation and favourable treatment outcome following standardized antituberculous treatment regimen confirmed the diagnosis of specific synovitis, which was also demonstrated by Magnetic Resonance Imaging (MRI). CONCLUSION: Tuberculous synovitis is important differencial diagnosis in patients with arthropathies and risk factors for TB in all the countries and all patients' ages even when tuberculin skin test is negative.
