Millet seeds


In disseminated (miliary) tuberculosis, the chest X-ray may have many tiny opacities resembling millet seeds that are scattered throughout the lung fields – miliary tuberculosis. This life-threatening condition, affecting several organs, is due to spread of the tuberculosis bacterium via the blood stream.
The presence of many tiny spots resembling millet seeds in shape and size is not unique to miliary tuberculosis, certain fungal infections and some cancers that have spread to the lungs, for example, may give this look on chest X-ray.
