Intraspinal lipomas without associated spinal dysraphism

Abstract

Introduction: The aim of this study was to report surgical strategies and clinical outcomes for thoraco-lumbar intradural lipomas. Intraspinal lipomas are rare congenital histologically benign neoplasms, which account for less than 1% of all spinal cord tumors. These tumors are most frequently found in the lumbosacral area as components of a dysraphic state, however, intramedullary lipomas are not associated with spina bifida or cutaneous malformations and have only been described as isolated cases among spinal lipomas, where the thoracolumbar region is rarely affected. Case Presentation: Three patients with thoracolumbar intradural lipomas were admitted to our clinic at different points of time. Partial resections and debulking of the tumors were achieved with the guidance of an operating microscope. We performed laminectomies or laminoplasties, for tumor resections. Discussion: Postoperatively, the patients demonstrated significant clinical improvements. In this manuscript we presented our surgical experiences for intraspinal lipomas. © 2014, Iranian Red Crescent Medical Journal.
