Epidural extraskeletal Ewing sarcoma. Case report and literature review

Abstract

Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented.
