A 15-year-old female experiencing lumbar pain without prior trauma. Despite being prescribed strong analgesics by her family physician, the symptoms intensified, and she was referred to diagnostic imaging. Magnetic resonance imaging revealed an intradural extramedullary tumor in the spinal canal, located behind the L3 corpora. The patient underwent neurosurgery with a complete resection of the tumor. The histopathologic examination revealed Ewing sarcoma by identifying EWSR1 gene in the extracted tissue. The patient was subsequently referred for extensive specialized oncological treatment including photon irradiation therapy and chemotherapy. Thirty-six months on from the initial diagnosis, the patient is doing well and suffers no sequelae apart from hypogonadism.
