CT Observation of Bone and Joint in chronic brucellosis

CT findings of bone,joint and spinal collumn of 27 cases with chronic brucellosis were analyzed,scanning sites including spinal column,sacro-iliac,hip,knee shoulder and elbow joints.Six of them had been documented for 8 years. The characteristic features were: (1) Lesions invaded multiple sites,multiple joints and various tissues with steady or insidious progression ; (2) Local or multiple destructive areas of subchondral bone of big joints could be found usually with significant circumferential zones of sclerotic bony reactions; (3) New,tiny destructive areas could al ways be found in those sclerotic zones and in the area of subperiosteal bony proliferations;and (4) Widening, narrowing or even obliteration of joint space, ossification of articular cartilage,loose-bodies,and calcification of synovial capsules could be seen in the invaded joints.
