There are several causes of miliary nodules, the most clinically profounded being respiratory disseminated tuberculosis - miliary tuberculosis.  As with many aspects of good clinical medicine, the correlate with patient's symptomatology is essential.

The appearances of both the chest x-ray and CT chest are classical with innumerable pin-point ( millet seed like ) nodules.

Additional evidence of tuberculosis is evident in the form of the chest wall cold abscess ( the source of the AFFB confirming the diagnosis ) and both supra and infradiaphragmatic lymphadenopathy.

Additional support of multisystem tuberculosis is the widespread intracerebral tuberculomas.
