ABSTRACT

Purpose. Review of cases of Ewing’s sarcoma diagnosed by the Hospital San Jose Tec de Monterrey radiology and imaging department from 1994 through 2009. We analyzed radiological manifestations and the main sites of presentation, in addition to conducting a bibliographic review of the topic.
Material and methods. Retrospective study of 9 patients with Ewing’s sarcoma (6 men and 3 women) diagnosed at between 4 and 23 years. Analysis of forms of presentation, radiological findings (x-rays, computed tomography, and magnetic resonance).
Results. Nine patients were identified with diagnosis of Ewing’s sarcoma; site of presentation predominantly around the pelvis and sacroiliac region, and in second place the lower limb. One case of extraosseous Ewing’s sarcoma was diagnosed, as well as one costal: Askin’s tumor.
Conclusions. Ewing’s sarcoma is the second leading cause of bone tumors in pediatric patients. When it is suspected, clinical studies should be performed to achieve a better assessment. Today it is evaluated by simple x-rays, but magnetic resonance and computed tomography are more useful because they determine the anatomy and extent of bone lesions; also, they provide the basis for planning treatment.
