Recurrent Mycobacterium marinum tenosynovitis of the wrist mimicking extraarticular synovial chondromatosis on MR images.
Tenosynovitis caused by atypical mycobacterial infections may produce rice bodies within affected tendon sheaths. We report a case of recurrent M. marinum infection involving the flexor tendons within the carpal tunnel in which the rice bodies were mistaken for synovial chondromatosis on MR images.
