Web patients typically present between the ages of 15 to 25 years with regional pain and swelling. Web this pattern describes a lytic lesion with periosteal reaction and cortical disruption at or near the metaphysis (a) sunburst appearance of osteosarcoma. It’s also important to distinguish both of these sunburst patterns from the sunburst sign of meningioma vascularity. The most common types of periosteal response encountered with osteosarcoma are the “sunburst” type and a codman triangle; 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). Five such cases are reported and discussed, i. 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. Web periosteal sunburst spiculation is a peculiar radiographic feature of osteosarcoma, and it represents a reactive ossification resulting from the action of normal osteoblasts rather than tumor cells.

Physical examination is notable for tenderness upon palpation above the right knee. The lamellated (onionskin) type of reaction is less frequently seen ( fig.

Web sunburst pattern due to new bone formation in soft tissue prognostic factors complete surgical resection with wide margins has been reported as the most significant prognostic factor Medullary and cortical bone destruction. Web patients typically present between the ages of 15 to 25 years with regional pain and swelling. 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. Web he has been having pain in this area for the past few months, has progressively worsened, and persists in the night. Web conventional radiography continues to play an important role in diagnosis.
