Abstract: | Cauda equina nerve sheath tumors are usually small, well-encapsulated tumors. Sometimes they may attain very large proportions, cause extensive bony changes, and resemble ependymomas in the cauda equina. They may also infiltrate into adjacent soft tissue planes and retroperitoneal spaces and yet be histologically benign. An awareness of this entity ensures aggressive surgical removal at the time of exploration. Primary neuro-fibrosarcomas or malignant changes in primary nerve sheath tumors of the cauda equina are seen in patients with neurofibromatosis. |
