Milky nodules are tiny nodules that appear as millet-like on chest radiographs or CT of the lungs, and generally refer to tiny nodules that are solid in density and less than 0.5 cm in diameter. They are usually caused by lung infections or metastatic tumors. Multiple chestnut nodules in both lungs are commonly seen in acute cornified tuberculosis, pneumoconiosis, lung metastases, and simple inflammatory nodules.
