Objective: The authors report a rare case of disseminated tuberculosis which had compromised the long head of biceps tendon and shoulder joint, during standard drug therapy. Methods: On a first sight, the accurate diagnosis wasn't accomplished and the patient had been treated with physiotherapy for rotator cuff tear. However, the patient presented with a fast growing mass in anterior region of the proximal third of the arm, complaining of pain increase. Aspirative punction of the mass revealed a yellow fluid and the laboratorial analysis confirmed infection by M. Tuberculosis. The patient was treated with surgical debridement and his drug therapy was changed. Results: Resolution of infectious status and complete shoulder function restoration was succeeded. Conclusion: Due to its high prevalence in Brazil, tuberculosis must always be considered as a possible cause of inflammatory joint disease, even in immunocompetent patients.
RESUMOObjetivo: Relatar um caso raro de tuberculose disseminada em paciente imunocompetente, que evoluiu, durante o tratamento medicamentoso padrão, com envolvimento do tendão da porção longa do bíceps e da articulação do ombro. Métodos: À primeira avaliação, o diagnóstico correto não foi feito e o paciente foi tratado com fisioterapia para tendinopatia do manguito rotador. Entretanto, apresentou rápida formação de massa na região anterior do terço proximal do braço e piora da dor. A punção da massa revelou líquido amarelado, cuja análise laboratorial confirmou tratar-se de infecção por M. tuberculosis. Resultados: O paciente foi tratado com desbridamento cirúrgico e troca do esquema medicamentoso e evoluiu com resolução do quadro infeccioso e melhora completa da função do ombro direito. Conclusão: Devido a sua alta prevalência no Brasil, a tuberculose deve sempre ser considerada no diagnóstico diferencial dos casos de comprometimento crônico e progressivo das articulações, ossos, músculos, tendões e bursas, mesmo em indivíduos imunocompetentes.
