Adolescence and. Web the sunburst appearance occurs when the lesion grows too fast and the periosteum does not have enough time to lay down a new layer and instead the sharpey's fibers stretch out perpendicular to the bone. When a bone lesion grows too quickly, the membrane covering the affected bone’s outer surface (the periosteum) may not have enough time to lay.
