With about 800 new cases diagnosed each year in the united states, this disease is rare but devastating. Web when the fibers turn into bony tissue (ossify), they can produce a pattern that’s known as a “sunburst periosteal reaction” or a “sunray periosteal reaction.” sunburst periosteal reactions are often caused by osteosarcoma but can also result from other conditions producing aggressive bone lesions, such as ewing’s sarcoma and. Osteosarcoma is most often found in the long bones — more often the legs, but sometimes the arms — but it can start in any bone. Web the osteogenic pattern almost always shows an area of the typical sunburst appearance, which on radiography is seen as stippled bone pattern with destruction of the cortical outlines and perpendicular striae (sharpey’s fiber) of. Web in conventional osteosarcoma, the tumour invades the periosteum to give rise to the classic 'sunburst appearance', caused by many thin irregular spicules of new bone developing outwards from.
