Case Discussion

Miliary TB refers to widespread dissemination of TB by hematogenous spread. It occurs in 2-6% of primary TB and also occurs somewhat more frequently in reactivation TB. In the latter situation, miliary TB may be seen in association with typical parenchymal changes or may be the only pulmonary abnormality.
