Extrapulmonary tuberculosis

It accounts for an increasing fraction of active cases, from 20 to 40% according to published reports,[2] and causes other kinds of TB.

[4] Extrapulmonary TB occurs more commonly in immunosuppressed persons and young children.

Infection of the lymph nodes, known as tubercular lymphadenitis, is the most common extrapulmonary form of tuberculosis.

It occurs during acute phases of the disease, with fever, cough, and pain while breathing (pleurisy).

Other diagnostic tests include the detection of adenosine deaminase (above 40 U/L) and interferon gamma in pleural fluid.
