Peritumoral brain edema in intracranial meningiomas.
Occurrence of peritumoral brain edema (PBE) in meningiomas has been associated with several factors in recent years, although its pathophysiological mechanism has not yet been fully elucidated. The aim of this study was to analyze the correlation between the presence / degree of PBE and factors such as gender, age, size and histological subtype of tumor. We analyzed the MRI images of 74 patient...
متن کاملRole of vascular endothelial growth factor and matrix metalloproteinase-9 in peritumoral brain edema associated with supratentorial benign meningiomas Running Title: Peritumoral Brain Edema with Meningiomas
Background: Accumulating evidence indicates that vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) play a central role in the development of peritumoral brain edema (PTBE) associated with human brain tumors. However, the roles of these proteins, particularly of MMP-9, in PTBE associated with benign meningiomas have not been elucidated. Objective: We investigated t...
متن کاملPeritumoral Brain Edema
R. Ricci A. Bacci V. Tugnoli S. Battaglia M. Maffei R. Agati M. Leonardi BACKGROUND AND PURPOSE: Little is known about the metabolic properties of brain edema associated with tumors. This work was conducted on the basis of the assumption that, in the presence of intra-axial and extra-axial brain tumors, the white matter involved by the edema is a site of metabolic change that involves the struc...
متن کاملExpression of MMP-9 and VEGF in Meningiomas and Their Correlation with Peritumoral Brain Edema
Meningiomas constitute up to 13% of all intracranial tumors. The predictive factors for meningioma have not been unambiguously defined; however some limited data suggest that the expression of matrix metalloproteinases (MMPs) and vascular endothelial growth factor (VEGF) may be associated with the presence of peritumoral brain edema (PTBE) and worse clinical outcome. The aim of this study was t...
متن کاملPredictors of peritumoral edema after stereotactic radiosurgery of supratentorial meningiomas.
OBJECTIVE Anecdotal evidence suggests that radiosurgical ablation of parasagittal meningiomas may be associated with increased risk of subsequent edema. Potential predictors of postradiosurgical peritumoral edema, including parasagittal tumor location, tumor size, and treatment dose, were evaluated. METHODS We retrospectively reviewed records of 102 patients with 111 supratentorial meningioma...
