Sunray Appearance: Osteosarcoma

If the lesion grows rapidly but steadily, the periosteum will not have enough time to lay down thin shell of bone, and in such cases, the tiny fibers that connect the periosteum to the bone (Sharpey's fibers) become stretched out perpendicular to the bone. When these fibers ossify, they produce a pattern sometimes called "sunburst" periosteal reaction.
