Materials and methods The patient was evaluated with preoperative lumbosacral CT and MR imaging and postoperative lumbosacral MR imaging. Results The lesion was hyperdense on CT, isointense on T1- and T2-weighted MR images, and enhanced homogeneously after intravenous gadolinium injection. With these CT and MR findings, surgery was performed with a presumptive diagnosis of nerve sheath tumor, but the histopathological examination revealed EES. Chemotherapy and radiotherapy were planned postoperatively. Conclusion This case illustrates that even in benign looking lesions in a neuroforamen one can never exclude malignancy, and this is even more true in a population of young adults.eninfo:eu-repo/semantics/closedAccessExtraskeletal Ewing SarcomaNeural ForamenSpineCtMriRetracted: Ct and Mr Findings in a Neuroforaminal Extraskeletal Ewing Sarcoma Mimicking Benign Nerve Sheath Tumor (Retracted Article.
