MAGNETIC RESONANCE IMAGING AND PATHOLOGICAL CORRELATES OF MENINGIOMAS
Main Article Content
Abstract
Objectives: To evaluate characteristics of meningiomas on magnetic resonance imaging in the differential diagnosis of benign and atypical/malignant meningiomas. Subjects and methods: cross-sectional description, 73 patients diagnosed with the meningioma, had surgery and pathology results were meningioma at Viet Duc Hospital and 103 Military Hospital from October 2020 to March 2021. Results: 56/73 cases were mostly benign; account for 76.7%. Atypical and malignant meningiomas accounted for 23.3%. Grade II atypical meningiomas had diffusion restriction on DWI, with 16/17 tumors accounting for 94.1%, while this rate in grade I menigiomas was 33.9%. This difference was statistically significant, p <0.05. Conclusion: diffusion-weighted was a valuable technique in predicting benign/malignant properties of meningiomas before surgery.
