It is frequently associated with osteosarcoma but can also occur with other aggressive bony lesions: The spiculated pattern is linked to aggressive lesions which strip the periosteum from the cortical bone, leaving behind a loose attachment of residual sharpey’s fibres between them. Web conventional radiography continues to play an important role in diagnosis. The angiographic findings in this tumor and their relationship to the pathologic appearance are discussed. 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.
