We learnt that the need of combination of some modalities together to diagnose an infectious syndrome.

Starting from a pulmonary localisation (primary infection), M. tuberculosis can spread to other organs during a silent phase, usually soon after primary infection. Active TB can develop in many other parts of the body, particularly in lymph nodes, meninges, bones and joints, kidneys, genital organs and the abdominal cavity.

Approximately 16% of global TB cases are classified as EPTB, although this figure varies according the local epidemiology [1]Citation 1.World Health Organization. Global Tuberculosis Report 2020. Geneva: World Health Organization; 2020.
