Abstract Primary malignant sarcomas of the spine are extremely rare. Because of biological heterogeneity, these tumors have variable sensitivity to radiation and chemotherapy. Presentation of severe radicular pain with MRI findings of an exradural lesion with extension through the neural foramen is rare to be an ewings sarcoma in any neurosurgeons carrier. We report about an eighteen years old female with primary Ewing´s sarcoma of the lumbosacral region which has been reported only a few times in literature.
