[Magnetic resonance imaging in the diagnosis of tuberculous arthritis].

A complex of clinical radiation and MRI studies of the joint was conducted in 45 patients with tuberculous arthritis. Two major forms of tuberculous lesion of the joint were identified: primary osseous tuberculous arthritis (79.6%) and tuberculous allergic synovitis (20.4%). In patients with tuberculous allergic synovitis, MRI revealed a nonspecific exudative proliferative response of the synovial membrane and edema of the bone marrow and periarticular tissues. In primary osseous tuberculous arthritis, MRI showed tuberculous inflammation foci in the epiphysis of the bone; proliferative changes in the synovial membrane, destruction of cartilaginous, fibrous, and osseous structures, as well as periarticular abscesses.
