Skip metastasis of intradural Ewing’s sarcoma in the lumbar spine: illustrative case
This case highlights the aggressive nature of intradural extramedullary Ewing's sarcoma and its propensity for early recurrence and metastasis. Although this presentation is extremely rare, postoperative adjuvant radiotherapy and chemotherapy, including craniospinal irradiation, should be considered to reduce recurrence risk. Frequent follow-up imaging is essential for the early detection of metastatic disease. https://thejns.org/doi/10.3171/CASE25361.
