Tuberculous Tenosynovitis Of The Wrist Joint: Imaging Findings On MRI

Naveen Rajadurai

Tuberculosis of the musculoskeletal system is uncommon and presents in 10% of extrapulmonary tuberculosis. Although atypical presentation of TB includes spine (51%) pelvis (12%), hip and femur (10%), knee and tibia (10%), and ribs (7%), tuberculous infection of the wrist is rare. Tuberculosis still remains the primary cause of tendon sheath infection even though it is an uncommon site of extra-articular TB. Due to its delayed initial diagnosis and because it mimics many other disease processes, many complications arise secondary to tuberculous tenosynovitis. Median nerve compression leading to carpal tunnel syndrome may also occur in these patients. This report discusses the imaging findings on MRI of a patient who presented with wrist swelling and was confirmed to have tuberculosis of the wrist on histopathological examination.
