Abstract
Introduction
We report the CT and MR findings in a 30-year-old man with extraskeletal Ewing sarcoma (EES) involving the left neural foramen at L5–S1 level.
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.
