Ewings Sarcoma Mimicking a Schwannoma: MRI Findings of a Rare Case

Abstract

• Ewing’s sarcoma is among the most frequent yet highly aggressive neoplasms of the bones presenting in adolescents and children under the age of ten with a slight male predilection. It is now broadly categorized into a set of tumors recognized as Ewing’s sarcoma family based on the same histology and genotype of these tumors. This group of tumors includes Ewing’s sarcoma of bones, the 2nd most frequent bone malignancy, Askin tumors, PNET, and those rarely occurring extraosseous Ewing sarcoma (peripheral neuroepithelioma). Extra-osseous Ewing’s is a rare presentation occurring in only 5% of patients. Here we present such a case of an extra-osseous Ewing’s sarcoma in a 13-year-old female presenting to our hospital with a large mass in the sacral region. The interesting imaging findings and his histopathology are discussed.
