Brain:
The central nervous system is made up of the brain and the spinal cord. TB bacilli can infect both, and cause TB meningitis – an infection of the thin layer that covers the brain.
Spine:
Pott disease is spinal infection, which begins in a vertebral body and often spreads to adjacent vertebrae
Gastrointestinal:
Rare and can occur in the context of active pulmonary disease or as a primary infection with no pulmonary symptoms.
Bones and joints:
Weight-bearing joints are most commonly involved, but bones of the wrist, hand, and elbow may also be affected, especially after injury.
Liver:
Liver infection is common in patients with advanced pulmonary TB and widely disseminated or miliary TB
Pleural:
Pleural TB is TB of the thin skin surrounding the lungs. This external lining serves to separate the lungs from the wall of the chest cavity.
Pancreas:
Abdominal tuberculosis is a common form of extrapulmonary tuberculosis but involvement of the pancreas is very rare.
Urogenital Tract:
The insidious onset and non-specific constitutional symptoms of genitourinary tuberculosis (GUTB) often lead to delayed diagnosis and rapid progression to a non-functioning kidney.
