摘要: Object: Despite their benign characteristics, meningiomas are often accompanied by perifocal brain edema. The aims of this study to determine what kind characteristics on magnetic resonance (MR) image indicative a meningioma that produces edema and investigate the mechanism responsible for accompanying meningiomas. Methods: Fifty-one patients with were examined imaging (MRI), tumor size, location, shape margin, peritumoral rim, signal intensity T2-weighted (T2WI) compared correlated presence versus absence Surgical histopathology was also MRI findings Results: Shape T2WI multivariate analyses. Conclusion: Invasive pattern brain–tumor interface hyperintensity factors producing
