Tuberculosis of acromioclavicular joint: a case report

Abstract

Abstract Background Osteoarticular tuberculosis is a great masquerader presenting in varied forms and in atypical locations, and it is prone to misdiagnosis and missed diagnosis. Isolated acromioclavicular joint tuberculosis has been reported rarely. Case presentation A 19-year-old man presented with a chronic, mild pain, non-healing ulcer in right shoulder. Imaging of the shoulder revealed destruction of the acromioclavicular joint and histopathology confirmed the diagnosis of acromioclavicular tuberculosis. The patient underwent debridement, synovectomy and drainage of the abscess and recovered well with antitubercular therapy postoperatively. Conclusions Awareness of this uncommon presentation of osteoarticular tuberculosis may assist in earlier diagnosis. Especially, in endemic countries, osteoarticular tuberculosis should be considered as a differential diagnosis in all atypical presentations to avoid residual problems.
