Figure 15: Orbital metastases from Ewing's sarcoma: Treated case of Ewing's sarcoma of iliac bone presented with right eye proptosis. Fine-needle aspiration cytology of the orbital mass was consistent with disease recurrence. Positron emission tomography/computed tomography was done to assess the metastases and plan appropriate treatment. Maximum intensity projection image (a) confirms no other site of metastases. Computed tomography (b) and the fusion images (c and d) show soft-tissue mass in superior aspect of the right orbit with erosion of roof of orbit. Subsequently, a patient received radiotherapy to right orbit and posttherapy scan image (e) revealed complete metabolic response
