 | Media file 1: Radiograph of Ewing sarcoma of the os naviculare, a rare location for the tumor. This image depicts a significant periosteal reaction. |
 | Media file 2: Fusion magnetic resonance imaging (MRI) and positron emission tomography scan studies obtained with fluorodeoxyglucose (FDG) in a patient with a Ewing sarcoma of the left tibia. This image demonstrates the tumor is primarily confined to the bone, with a small periosteal fraction. The MRI findings matched those of the PET images obtained with FDG scanning. (See also Image 3.) |
 | Media file 3: Positron emission tomogram obtained with fluorodeoxyglucose (FDG) scanning at the level of the magnetic resonance image in Image 2. This image shows high FDG accumulation in the lesion, which indicates high tumor viability. Moderate FDG accumulation in the periosteum and soft tissue resulted from tumor involvement. |
 | Media file 4: Radiograph from an 11-year-old boy with a large Ewing sarcoma in the right pelvic area. Destruction of the bone structure resulted from tumor involvement. (See also Images 5-6.) |
 | Media file 5: Magnetic resonance images from an 11-year-old boy with a right pelvic Ewing sarcoma (same patient as in Images 4 and 6). The tumor in the right iliac bone has the typical hyperintense appearance and extends to the hip. Significant involvement of the soft-tissue structures is depicted. |
 | Media file 6: Cross-sectional positron emission tomograms obtained after the administration of fluorodeoxyglucose (FDG). The images correspond to the magnetic resonance image in Image 5. These tomograms depict increased metabolic activity in the tumor, as well as in the surrounding soft-tissue area. |
 | Media file 7: Cross-sectional fusion magnetic resonance image (MRI) and positron emission tomographic image of a Ewing sarcoma. The highest metabolic activities match the MRI findings. Note the soft-tissue involvement resulting from the large tumor. |
