Ewing sarcoma is the second most common primary malignant bone tumor that usually affects diaphysis of long bones during the second decade of life. Isolated unilateral orbital metastasis from this tumor presenting as proptosis is extremely rare. Here we report a case of 11-year-old boy where whole-body FDG PET/CT scan detected primary an Ewing sarcoma site in the left femur and isolated orbital metastasis in the left eye. Follow-up PET/CT scan after 6 cycles of chemotherapy showed resolution of the previously seen lesions.
