Primary Spinal Intradural Ewing's Sarcoma: Hemorrhagic Presentation with Acute Neurological Deterioration in Two Pediatric Patients.

Extraosseous primary spinal intradural Ewing's sarcoma (ES) is an unusual entity. Bleed within such tumors with acute neurological worsening is extremely rare, especially in the pediatric age. In this article, we present two children with intradural-extramedullary ES who had sudden decline in their neurological status consequent to an intratumoral hemorrhage. We discuss their clinical course and also briefly review the pertinent literature. Spinal intradural Ewing's sarcomas possibly have a tendency to bleed. A short clinical symptomatology along with an acute neurological deterioration and radiologic evidence of intratumoral hemorrhage in a spinal intradural tumor should raise the suspicion of an ES.
