Osteosarcoma Sunburst Pattern

Osteosarcoma Sunburst Pattern - Web he has been having pain in this area for the past few months, has progressively worsened, and persists in the night. 1,2 osteosarcomas are defined by the production of osteoid, or immature bone, by malignant mesenchymal cells. Web the associated soft tissue mass can exhibit variable patterns of ossification, leading to the characteristic radial sunburst pattern often associated with 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. Diagnosis is made with radiographs showing a lesion that has a classic sunburst or hair on end periosteal reaction with biopsy showing cellular atypia with areas of osteoid and chondroblastic matrix. Atypical mitotic figures are frequently present. 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 four types can be distinguished: Similar content being viewed by others. Osteosarcoma does not cross the joint space to affect other bones in the joint.

Web the angiographic analogue of the ‘sunburst’, (right angle) periosteal new bone formation in osteogenic sarcoma is described. Web patients typically present between the ages of 15 to 25 years with regional pain and swelling. The sunburst appearance occurs when the lesion grows too fast. 1,2 with about 800 new cases diagnosed each year in the united. Patients are typically children, teenagers or young adults who present with rapidly progressive pain and swelling. A radiograph of the distal thigh demonstrates a sunburst pattern and codman triangle. Web conventional radiography continues to play an important role in diagnosis. 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. It is frequently associated with osteosarcoma but can also occur with ewing sarcoma or osteoblastic metastases. The most common types of periosteal response encountered with osteosarcoma are the “sunburst” type and a codman triangle;
