Management of spinal meningiomas: surgical results and a review of the literature (original) (raw)

2007, Neurosurgical FOCUS

ENINGIOMAS are typically benign, slowly growing tumors. Despite the fact that their histogenesis is unclear, it is thought that arachnoidal cells are the most likely origin of these lesions. Meningiomas account for 13 to 19% of all intracranial tumors. Spinal meningiomas represent 12% of all meningiomas 31 and 25 to 45% of intradural spine tumors. 14 Spinal meningiomas lead to chronic spinal cord compression and myelopathy. Treatment is predominantly surgical. Previously published data indicate mostly favorable outcomes; however, progressive spinal cord compression due to a spinal meningioma can lead to neurological deterioration that, at times, can result in a permanent deficit even after successful surgery. In this article we review our experience at two neurosurgical centers with the surgical management of spinal me-ningiomas with particular attention given to surgical techniques, adjuvant therapies, prognostic factors, recurrence rates, and long-term outcomes. Furthermore, we reviewed the literature as it pertains to the surgical treatment of these tumors.
