Intramedullary Neurilemmoma in Conus Medullaris

A case of intramedullary neurilemmoma embedded within the conus medullaris of spinal cord and presumably extending over its surface, is reported. Published reports of these rare lesions and possible mechanisms of their origin are reviewed. The treatment of choice for these rare lesions is thought to be laminectomy and resection and intraoperative frozen section diagnosis is considered essential. Importance of operative removal is emphasized.
