Miliary tuberculosis is an uncommon pulmonary manifestation of tuberculosis. It represents haematogeneous dissemination of uncontrolled tuberculous infection and carries a relatively poor prognosis.
It is seen both in primary and post-primary tuberculosis and may be associated with tuberculous infection in numerous other tissues and organs.
Miliary deposits appear as 1-3 mm diameter nodules, which are uniform in size and uniformly distributed.
Similar findings to plain film but may more elaborately show extent and distribution.
Treatment and prognosis
If treatment is successful no residual abnormality remains.
