Background
Tuberculosis (TB) has re-emerged as a global public health emergency, largely due to the AIDS epidemic.
Abdominal TB is usually due to mycobacterium tuberculosis or mycobacterium avium in the immunocompromised host.
Thoracic TB may suggest associated abdominal TB, however only 15% with abdominal disease have evidence of pulmonary TB.
TB can affect any organ and we present imaging features of solid viscera, ileocaecal, peritoneal and lymph node involvement.

THE "GREAT MIMIC"
Abdominal TB mimics many conditions both clinically and radiologically and can result in significant morbidity.
Familiarity with the imaging features and complications of the disease is essential in order to allow early diagnosis and treatment and ensure a favourable outcome.
This presentation examines imaging findings that will help to differentiate this condition from those it mimics, inflammatory and neoplastic, such as Crohn’s disease and lymphoma.
