 | Media file 1: Radiograph of the femur in a patient with osteosarcoma shows a typical Codman triangle (arrow) and more diffuse, mineralized osteoid within the soft tissues adjacent to the bone. |
 | Media file 2: Lateral radiograph of the distal femur in a child with osteosarcoma involving the metaphysis and metadiaphysis. Note the abnormal texture and mild sclerosis of the distal femoral shaft; the aggressive periosteal changes, including Codman triangles (white arrow); and the large soft tissue mass (black arrow). |
 | Media file 3: Sagittal T1-weighted MRI (see also Image 2 in the Multimedia Section). The signal intensity of the bone marrow within the distal femoral epiphysis is normal, but abnormal signal intensity is present throughout the visible shaft. The growth plate has limited extension of the tumor. Cortical destruction (arrow) and the soft tissue mass may be readily appreciated. Note that the fat deep to the quadriceps tendon has rather heterogeneous signal intensity. |
 | Media file 4: Sagittal short-tau inversion recovery (STIR) MRI (see also Images 2-3 in the Multimedia Section; compare the MRI appearances with that of Image 3). Note the increased signal intensity (arrow) throughout the reactive zone within fat deep to the quadriceps tendon. Microinvasion by tumor and reactive edema cannot be differentiated in these areas. |
 | Media file 5: Axial T1-weighted MRI (see also Images 2-4 in the Multimedia Section). The abnormal medullary signal intensity (white arrow) and the soft tissue mass (black arrow) are identified. |
 | Media file 6: Axial short-tau inversion recovery (STIR) MRI (see also Images 2-5 in the Multimedia Section). The abnormal medullary signal intensity (black arrow) and the soft tissue mass (white arrow) are identified. |
 | Media file 7: Anteroposterior (AP) radiograph of the proximal tibia in a child with osteosarcoma involving the metaphysis. The tumor is densely sclerotic, but an area of lucency and cortical destruction is shown proximally on its lateral margin. Scalloping of the cortex is observed inferior to this area, with amorphous mineralized osteoid shown in the soft tissues (arrow). Note that the tumor appears to be superiorly confined by the growth plate. |
 | Media file 8: Coronal T1-weighted MRI (see also Image 7 in the Multimedia Section). Note the abnormal signal intensity in the metaphyseal marrow and the soft tissue mass (black arrow). Early tumor extension is shown beyond the growth plate into the epiphysis (white arrows). |
 | Media file 9: Lateral radiograph of the calcaneum in an adult with osteosarcoma shows a predominantly lucent lesion in the anteroinferior part of the bone and cortical destruction. |
 | Media file 10: Lateral isotope bone scan (see also Image 9 in the Multimedia Section) reveals intense uptake in the calcaneal region. The remainder of the skeleton appeared normal. |
 | Media file 11: Sagittal T1-weighted MRI (see also Images 9-10 in the Multimedia Section). The true extent of the lesion within the calcaneum may be better appreciated on this image than on the radiograph. Extension into the sinus tarsi and calcaneocuboid joint is also shown. |
 | Media file 12: Anteroposterior (AP) radiograph in a patient with osteosarcoma of the proximal humerus. Note the extensive soft tissue mass containing a considerable amount of mineralized osteoid. |
 | Media file 13: Anteroposterior (AP) radiograph of the shoulder in a patient with osteosarcoma of the scapula. Note the extensive cortical destruction, aggressive periosteal changes, and soft tissue ossification of the acromion and upper scapula. |
 | Media file 14: Lateral radiograph of the distal femur in an adult patient with osteosarcoma appearing as a pathologic fracture. |
