Carpal tunnel syndrome secondary to tuberculous tenosynovitis

: A case of tuberculous flexor tenosynovitis causing a carpal tunnel syndrome is described. Surgery initially relieved the patient's symptoms, but the disease process continued until the diagnosis was made and appropriate treatment was instituted. This diagnosis, although rare, should be considered as the etiology in a carpal tunnel syndrome, particularly when there is evidence of a proliferative tenosynovitis and radiographs show diffuse osteoporosis.
