Role of computed tomography scanning in the management of Ewing's sarcoma.
It is well established when imaging patients with primary bone malignancy that on occasions computed tomography (CT) scanning can offer unique information. It is less clear, however, in what circumstances this information will lead to a change in patient management. This study reviewed the results of CT examinations in 32 patients with Ewing's sarcoma and examined the influence of CT on patient management in different clinical circumstances. CT provided new information on a total of 75 occasions out of 153 examinations. Management was changed on 17 occasions as a direct result of the CT scan findings. Overall, 50% of patients had their management altered as a result of CT. Follow-up CT scans in the chest more frequently influenced patient management than did either staging or follow-up scans of the primary site.
