Vanishing lesion associated with cauda equina ependymoma

Ependymomas are relatively rare tumors of neuroectodermal rigin. They account for 5–10% of central nervous system primitive umors [1] and 35% of them occur in spinal cord [2]. Conus medullaris, cauda equina and filum terminale ependyomas are in the majority of the cases (87–95%) myxopapillary pendymomas [1]. Their clinical presentation depends on their location, but their maging features are usually evocative above all in multifocal ocation [1]. However acute neurological deficit caused by sponaneous hemorrhage arising from a cauda equina ependymoma is xceptional. We report a case of acute incomplete cauda equina yndrome related to two distant processes of cauda equina mimickng multifocal ependymoma. A vanishing supposed ependymoma as diagnosed only after surgical approach of the most compresive and voluminous lesion.
