Imaging of musculoskeletal tuberculosis: a new look at an old disease.

There are certain imaging features that help to differentiate tuberculosis from other bone and joint disorders with a similar presentation. The current authors discuss these distinguishing imaging features particularly with respect to ultrasound, computed tomography, and magnetic resonance imaging. The judicious and appropriate use of these newer imaging modalities coupled with aspiration or biopsy can lead to earlier recognition of musculoskeletal tuberculosis before the onset of debilitating disease.
