Osteosarcoma Sunburst Pattern

Osteosarcoma Sunburst Pattern - Medullary and cortical bone destruction. It’s also important to distinguish both of these sunburst patterns from the sunburst sign of meningioma vascularity. Web the conventional plain radiograph is the best for probable diagnosis as it describes features like sun burst appearance, codman's triangle, new bone formation in soft tissues along with permeative pattern of destruction of the bone and other characteristics for specific subtypes of osteosarcomas. Web permeative and destructive growth pattern. Solid, lamellated, spiculated and codman's triangle [1,2]. A radiograph of the distal thigh demonstrates a sunburst pattern and codman triangle. Localized widening of the periodontal ligament space of 1 or 2 teeth in the absence of dental disease may occur in an early stage of osteosarcoma. 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’s important to distinguish a sunburst periosteal reaction from a sunburst (or honeycomb) trabeculation, which is a different type of finding indicating an intraosseous hemangioma. It is frequently associated with osteosarcoma but can also occur with other aggressive bony lesions:

A radiograph of the distal thigh demonstrates a sunburst pattern and codman triangle. Medullary and cortical bone destruction. Web permeative and destructive growth pattern. 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 periosteal reaction. 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. Formation of new bone in a sunburst pattern; The lamellated (onionskin) type of reaction is less frequently seen ( fig.
