Organism may enter in the pulmonary venous return to the left site of the heart and from here it may spread to almost every organ of the body. Disseminated tuberculosis is defined as a hematogenous transmission of the bacilli with active caseous tubercle formation in two or more extrapulmonary sites and with no pulmonary miliary nodular shadowing on chest radiography (Penner et al. Epididymal tuberculosis 8. All medicines are continued until lab tests show which work best. Changes in the early stages may be subtle and alternate sources to the lung, such as blood, bone marrow, or liver biopsy, should be sought if miliary TB is suspected. The causative agent is Mycobacterium tuberculosis (also known as the tubercle bacillus). Thus, this stage of the infection is defined after the pathogen is isolated from at least two noncontiguous organs like bone marrow, liver, blood, kidney, brain, scrotum or lungs.
