Peritumoral edema and prognosis in intracranial meningioma surgery

Abstract Peritumoral brain edema (PTBE) is often associated with meningiomas. PTBE is probably implicated in the complications occurring in intracranial meningiomas. The goal of this study was to determine the exact implication of PTBE in prognosis. Thirty consecutive patients who underwent surgery for intracranial meningiomas were investigated over a 1-year period. We focused on the clinical and radiological status before and after surgery, and postoperative complications. Multiple regression analysis revealed a close correlation ( p
