Extrapulmonary tuberculosis

Extrapulmonary tuberculosis is an infection outside of the lungs that is caused by tuberculosis (TB) bacteria.

The most commonly affected areas include the:

  • Lymph nodes.
  • Reproductive or urinary tract organs.
  • Space between the lungs and the ribs (pleural space).
  • Bones and joints.
  • Areas throughout the body (miliary).
  • Tissues covering the brain and spinal cord (meninges).
  • Tissues lining the abdomen and covering the abdominal organs (peritoneum).

Extrapulmonary TB may involve more than one of these organs or systems. The bacteria may spread through the bloodstream.

People from certain regions (such as southeast Asia), people with human immunodeficiency virus (HIV), infants, and young children seem to have an increased risk for extrapulmonary TB.
