Signs and Symptoms
A patient with miliary tuberculosis will tend to present with non-specific signs such as low grade fever, cough, and generalized lymphadenopathy. Miliary tuberculosis can also present with hepatomegaly (40% of cases), splenomegaly (15%), pancreatitis (<5%), and multiorgan dysfunction with adrenal insufficiency.[1]

Common findings of miliary tuberculosis on chest x ray
- Fine, pin point approximately 1-2mm in size, discrete, uniform distribution, soft mottlings.
- Commonly found throughout both the lungs.
Treatment
Miliary TB is a serious condition; untreated miliary TB is almost always fatal. About 25% of patients with miliary TB also have tuberculous meningitis. The standard treatment recommended by the WHO is with isoniazid and rifampicin for six months, as well as ethambutol and pyrazinamide for the first two months. If there is evidence of meningitis, then treatment is extended to twelve months. The US guidelines recommend nine months' treatment.
