Extramedullary foramen magnum tumors and their surgical management: An experience with 29 cases.

摘要: Introduction: Surgical management of foramen magnum (FM) tumors is challenging by virtue their location and vital neurovascular relationships. The ideal approach to anterior/anterolateral continue evoke controversy even in the modern era. In this article, we present discuss our experience surgical these tumors. Materials Methods: This retrospective study includes 29 consecutive patients (mean age 36.6 years, M: F = 2.63:1) extramedullary at magnum, operated center, between 2007 2012. Results: Their mean duration symptoms was 14. 6 months. A majority presented with motor (quadri/paraparesis, n 21, 72.4%), neck pain with/without suboccipital radiation (n 16, 55.2%) sensory like tingling/numbness 55.2%). There were nine extradural (31%) 20 intradural (69%). Most located posterolateral neuraxis 13, 44.8%). Nerve sheath 11, 38%) meningiomas 5, 17.2%) most commonly encountered histologies series. standard posterior frequently employed 20, 69%). Operative mortality morbidity 3.4 18.9%, respectively. At a follow-up 27.3 months, 13 out 18 available improved. Conclusion: are amenable excision via approach. Small anterior dural-based meningiomas/recurrent may require lateral far
