[Miliary tuberculosis is difficult to diagnose].

An 82-year-old male was admitted for treatment for pneumonia after a few weeks of fever, cough and dyspnoea. Alternating treatment with different antibiotics had no effect on the condition and all common tests for tuberculosis were negative. An autopsy later revealed disseminated tuberculosis to lungs, retroperitoneal glands and liver. Miliary tuberculosis can in principle affect all organ systems and a wide variety of unspecific symptoms are seen. The differential diagnosis should be brought to the awareness of clinicians when complex symptomatology remains unaccounted for.
