• Abstract:

  Osteoarticular infection caused by Mycobacterium tuberculosis is more common in children and adolescents than in adults. A suggestive picture is monoarthritis with histopathology of the lesion demonstrating granulomatous reaction. Its diagnosis is suggested by family history or close contact with a positive person, positive Mantoux (80% of cases), positive synovial fluid culture (75%), biopsy with granulomatous reaction and positive synovial membrane culture in up to 90% In most cases, imaging exams can demonstrate bone destruction, cysts, cavitations.

  This paper presents a case report of a patient with monoarthritis in the hand, with a picture suggestive of infectious arthritis due to TB, but without biopsy confirmation and who evolved with a good response to the therapeutic test.
