Abstract

Background: Intradural extramedullary (IDEM) tumors account for two thirds of all primary intraspinal neoplasms. They mostly include schwannomas, meningiomas and ependymomas which are located circumferentially anywhere by the spinal cord. Since the clinical symptoms and histology of these tumors are mostly benign in nature, the primary goal of the treatment should be gross total resection without any functional deterioration.

Objective: In cases of intradural extramedullary tumors, surgery should be planned with respect to preservation of the stability and the anatomy of the spine without giving any harm to surrounding vital structures. Therefore, surgical policy should be planned thoroughly for the best outcome.

Methods: The authors shall discuss the surgical policy according to the localization of these neoplasms, especially the minimally invasive attempts in accordance with the most recent literature.

Results: IDEM spinal tumors is classified according to their relation with spinal cord and the denticulate ligament; posterior, posterolateral, lateral, anterolateral, and anterior. The trajectory and surgical techniques are discussed in detail in each group with cases of our own experience.

Conclusion: Surgical excision of these benign lesions should be planned according to the localization of the tumor in order to achieve gross total resection with minimal harm to vital structures.
