Musculoskeletal tuberculosis - imaging using low-end and advanced modalities for developing and developed countries.

Musculoskeletal involvement by TB is rare in comparison to other forms of the disease. It most commonly involves the spine but can also involve large weight-bearing joints, long bones, the skull and the soft tissues. Characteristic appearances of musculoskeletal TB are described for numerous imaging modalities in this paper but it is also highlighted that when based on imaging appearances alone, there is always a differential diagnosis, including other infections and malignancies.
