Ewing’s sarcoma

Ewing’s sarcoma: aggressive malignant tumor with a peak incidence during the second decade of life. Spine metastases are more common than primary spine lesions.

Treatment

Treatment is mostly palliative: radical excision followed by RTX (very radiosensitive) and chemotherapy 1).

The use of stereotactic body radiotherapy (SBRT) is well-accepted 2).

SRS for spine metastases from Ewing sarcoma can be considered as a treatment option in adolescent and young adult patients and is associated with acceptable toxicity rates. Further studies must be conducted to determine long-term local control and toxicity for this treatment modality 3).

Complications

SIADH.

Combined intracranial/extracranial lesions.

Case reports

Intradural Extramedullary Ewing's Sarcoma in the Cervical Region 4).


A 21-year-old woman presenting with quadriplegia which was initially diagnosed with an epidural abscess in view of her MR scan and raised inflammatory marker levels. Histology revealed an epidural extra-osseous Ewing's sarcoma (EES). Epidural location of EES is a very rare condition which can be very challenging to diagnose. Early diagnosis and surgical excision followed by chemotherapy represent the main stem of management 5).
