Primary intradural/extradural Ewing's sarcoma of the sacral spine: A case report and literature review.

BACKGROUND

Ewing's sarcoma (ES) is a malignant mesenchymal tumor, most often found in the long bones, and usually affecting children and adolescents in the second decade of life. ES of the spine is a clinical rarity.

CASE DESCRIPTION

A 45-year-old male presented with a 3-month history of lower back pain which acutely worsened in conjunction with urinary retention. The magnetic resonance imaging revealed a mass extending from L5 to S2 with additional extension through the left S2-3 neural foramen. The metastatic workup was negative. At surgery, the lesion was both intradural and extradural. Following complete surgical resection, the patient was later treated with radiation and chemotherapy.

CONCLUSION

Here, we report an adult male who acutely presented with low back pain attributable to primary intradural/extradural sacral ES.
