Osteosarcoma Sunburst Pattern

Osteosarcoma Sunburst Pattern - A pathologic fracture may be seen through the abnormal bone. 1,2 osteosarcomas are defined by the production of osteoid, or immature bone, by malignant mesenchymal cells. The most common types of periosteal response encountered with osteosarcoma are the “sunburst” type and a codman triangle; The lamellated (onionskin) type of reaction is less frequently seen ( fig. 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. Physical examination is notable for tenderness upon palpation above the right knee. Solid, lamellated, spiculated and codman's triangle [1,2]. 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. 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 conventional radiography continues to play an important role in diagnosis.

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. 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 permeative and destructive growth pattern. 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). 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.
