Web patients are typically children, teenagers or young adults who present with rapidly progressive pain and swelling. 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. A radiograph of the distal thigh demonstrates a sunburst pattern and codman triangle. Web patients typically present between the ages of 15 to 25 years with regional pain and swelling. Another pattern seen in rapidly growing processes is called the codman's triangle.
The lamellated (onionskin) type of reaction is less frequently seen ( fig. Physical examination is notable for tenderness upon palpation above the right knee. Formation of new bone in a sunburst pattern; Web when these fibers ossify, they produce a pattern sometimes called sunburst periosteal reaction. Web osteosarcomas are the most common primary bone tumor and third most common cancer among children and adolescents, behind lymphomas and brain cancers.
Web the associated soft tissue mass can exhibit variable patterns of ossification, leading to the characteristic radial sunburst pattern often associated with osteosarcoma. The angiographic findings in this tumor and their relationship to the pathologic appearance are discussed. The most common types of periosteal response encountered with osteosarcoma are the “sunburst” type and a codman triangle; Web metastatic bone tumors occasionally are found in association with a sunburst periosteal proliferation of bone resembling that of primary bone tumors. A pathologic fracture may be seen through the abnormal bone.

1,2 with about 800 new cases diagnosed each year in the united. Web this pattern describes a lytic lesion with periosteal reaction and cortical disruption at or near the metaphysis (a) sunburst appearance 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. A pathologic fracture may be seen through the abnormal bone. Web he has been having pain in this area for the past few months, has progressively worsened, and persists in the night. Osteosarcoma does not cross the joint space to affect other bones in the joint. 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). 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 ewing sarcoma or osteoblastic metastases. Five such cases are reported and discussed, i. 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. Web metastatic bone tumors occasionally are found in association with a sunburst periosteal proliferation of bone resembling that of primary bone tumors. 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.

Osteosarcoma Does Not Cross The Joint Space To Affect Other Bones In The Joint.
1,2 osteosarcomas are defined by the production of osteoid, or immature bone, by malignant mesenchymal cells. A radiograph of the distal thigh demonstrates a sunburst pattern and codman triangle. 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 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
