Spinal tumors which are classified as extradural, intradural extramedullary and intramedullary according to their localization are relatively rare tumors. The intradural extramdullary tumors account for the 70-80% of all spinal tumors. Schwanommas, neurofibromas and meningiomas are more commonly seen intradural extramedullary tumors. However paragangliomas, metastases,, lipomas, spinal nerve sheath mixomas, sarcomas and vascular tumors are more rarely seen intradural extramedullary tumors.

Surgical resection is the basis of the treatment, but gross total resection is not always possible due to the close proximity or sometimes direct adhesion of the tumor or the capsule of the tumor to neural structures. Today it is known that the risk of developing neurological deficits is significantly reduced with the use of intraoperative neuromonitoring. The use of radiotherapy for the treatment of intradural extramedullary lesions is quite limited becasuse of the risk of radiation necrosis, however it is recommeded in the presence of seeding or extensive hematogenous metastases.
