Atypical mycobacterial tenosynovitis of the wrist can easily be misdiagnosed as synovial chondromatosis. Both sonography and magnetic resonance imaging plays an important role in depicting "rice bodies" within the distended tendon sheaths and bursae of atypical mycobacterial infection. An endemic place for Mycobacterium species and the occupation of the patient should raise the suspicion for the disease. Polymerase chain reaction of the distended tendon fluid is a sensitive, specific and rapid method in identification of the mycobacteria.
