Osteosarcoma Sunburst Pattern

Osteosarcoma Sunburst Pattern - Conventional intramedullary osteosarcomas are malignant, aggressive, osteogenic bone tumors most commonly found in the knee and shoulder regions. 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. The most common types of periosteal response encountered with osteosarcoma are the “sunburst” type and a codman triangle; Osteosarcoma does not cross the joint space to affect other bones in the joint. Atypical mitotic figures are frequently present. 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 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 angiographic findings in this tumor and their relationship to the pathologic appearance are discussed. 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

A pathologic fracture may be seen through the abnormal bone. 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. The angiographic findings in this tumor and their relationship to the pathologic appearance are discussed. It is frequently associated with osteosarcoma but can also occur with other aggressive bony lesions: Web permeative and destructive growth pattern. 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. 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. Formation of new bone in a sunburst pattern; Web the associated soft tissue mass can exhibit variable patterns of ossification, leading to the characteristic radial sunburst pattern often associated with osteosarcoma. Web osteosarcomas are the most common primary bone tumor and third most common cancer among children and adolescents, behind lymphomas and brain cancers.
