Osteoarthritis of the ankle revealing disseminated tuberculosis

Tuberculosis is a major public health problem. It has a high annual incidence in Africa and Asia. The estimated number of new cases of tuberculosis is constantly increasing. The estimated number of new cases of tuberculosis (TB) is constantly increasing and will reach 10 million in 2019 [1]. Osteoarticular tuberculosis is rare and represents only 10-15% of extrapulmonary localisations. It is most often the result of haematogenous dissemination of BK. Extension to adjacent soft tissues with formation of cold abscesses is also observed. Its main location is in the axial region, which accounts for about 50% of cases [2]. Localization in the peripheral joints is less frequent. Tuberculous osteoarthritis of the ankle is very rare [3]. We report an original observation of an immunocompetent patient who developed disseminated tuberculosis with an osteoarticular origin, confirmed by the detection of the tuberculosis complex genome in synovial and bone tissue.
