gastrointestinal tuberculosis

Abdominal tuberculous can manifest in almost every abdominopelvic organ:

Pathology

There are three main pathways for tuberculous infection of the abdomen :

  • ingestion of infected milk or sputum initially affects gastrointestinal tract mucosa, followed by the remainder of the bowel wall, regional lymph nodes and peritoneum
  • haematogenous spread to the peritoneum, lymph nodes and solid viscera
  • direct spread to the peritoneum, e.g. from skeletal tuberculosis via a psoas abscess
