Background: Tuberculous tenosynovitis of the wrist is rare among cases of musculoskeletal
tuberculosis. It is a slow, progressive disease with silent symptoms, leading to a late diagnosis.
Also, it can be misdiagnosed as inflammatory arthritis, pyogenic infections, and inflammatory
tenosynovitis. Thus, patients present with destructive changes of the bone and joint, as well as
abscesses, often receive incorrect or unnecessary medical and surgical treatment.
Discussion: Well-documented anamneses along with physical examinations and radiologic imaging
methods, such as computed tomography (CT) and magnetic resonance imaging (MRI), can be
useful in the diagnosis of tuberculous tenosynovitis. All chronic synovitis of the wrist with longstanding
pain should be considered as mycobacterial infection and an important differential diagnosis.
Early diagnosis followed by extensive debridement and antituberculous chemotherapy provides
good functional results.
Conclusion: This article presents the cases of two patients with wrist tuberculous tenosynovitis and
the respective MRI findings. It also includes a literature review.
