Web some osteosarcomas show a periosteal reaction manifesting as a sunburst pattern caused by radiating mineralized tumor spicules or a triangular elevation of the periosteum (codman's triangle). It’s also important to distinguish both of these sunburst patterns from the sunburst sign of meningioma vascularity. 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. Web it is noted that the sunburst pattern tends to occur with rapidly growing tumors in which there is both bone and extraosseous involvement and that the response occurs near, but not immediately adjacent to, destructive tumor foci.
