The radiographic appearance of<unk>  on an X-ray is characterized by a pattern of numerous white densities of similar size spread throughout all the bones. This is a systemic condition. It must be differentiated from blastic metastasis, which can also present radiographically as white densities interspersed throughout bone. Blastic metastasis tends to present with larger and more irregular densities in less of a uniform pattern. Another differentiating factor is age, with blastic metastasis mostly affecting older people, and<unk>  being found in people 20 years of age and younger. The distribution is variable, though it does not tend to affect the ribs, spine, or skull.
