Disseminated Tuberculosis
Disseminated
tuberculosis is a mycobacterial infection, where mycobacteria have transmitted from the
lung to other body parts via the blood or lymph system, thus making it difficult to diagnose TB. Disseminated TB (disseminated tuberculosis) is characterized to include two or more non-contiguous sites that are the result of
Mycobacterium Tuberculosis lymphohematogenic dissemination. Extrapulmonary involvement is documented in one-fifth of all TB cases in which histological and radiological evidence of pulmonary
infection is absent. Disseminated TB is seen in developing countries, especially in children under the ages of 15, as a significant cause of
morbidity and mortality. However, due to several risk factors, it has become more common in most technically advanced countries and various age groups. These include HIV /
AIDS infection and other causes of immunosuppression, such as biologics and immunosuppressive medication for different
health disorders, increased prevalence of organ transplants, alcohol, chronic liver disease, chronic hemocytology,
diabetes mellitus, malignancies, and silicosis.
