extrapulmonale Manifestationen der Tuberkulose

Extrapulmonary tuberculosis (TB) refers to the haematogenous spread of Mycobacterium tuberculosis.


Extrapulmonary tuberculosis can occur as a primary form of the disease, i.e. direct infection of an extrapulmonary organ without the presence of primary pulmonary tuberculosis or it can occur as a result of the spread of primary pulmonary tuberculosis.

It appears classically as tuberculous granulomata (tuberculomas) within the affected organs. However, certain forms of the disease exist manifesting with specific findings:

Radiographic features

Widely variable dependent on the site of involvement. It is best to refer to site-specific articles.

As tuberculous organ infection can mimic malignant disease recent studies have reported the usefulness of FDG PET-CT in evaluating and following up patients in whom the diagnosis is in doubt .
