Background; Meningiomas begin from arachnoid meningothelial (top cells) of the arachnoid villi which are normally situated along dural venous sinuses. Most of meningiomas are unconstrained and of obscure etiology, albeit perceived chance elements incorporate past introduction to radiation, injury, hereditary issue. Meningiomas are characterized into three grades as indicated by World Health Organization (WHO) 2016 criteria. Considering the vagueness of the clear–cut demarcation and heterogeneity of the meningiomas its imperative that we gather more data and build on evidence. We employed a noninvasive, imaging classification technique , to associate the meningiomas with WHO grading and facilitate the diagnostic features evident on the MRI imaging for the Meningiomas. Methodology: The present study was a cross sectional study from Feb 2018 to Jan 2019 (11 months). Research study was conducted at Department of Radiodiagnosis & Imaging, RIMS Ranchi. A total 50 patients were part of the study. Department’s MRI Machine of 1.5T(Seimens Magnetom Symphony) was used . Data was collected on the questionnaire and analysis was done using the SPSS software version 16. We evaluated peritumoral brain edema and T2 signal hyperintensity of the tumours and its correlation. Results : A test for association using chi square was found to be significant statistically on comparing the Peritumoral brain edema (Radiologically evident) with Grading of the Meningioma visualized in the MRI . Occurrence of the meningioma was most in Parasagittal/falx region(30%) followed by convexities while other locations were also located on MRI . Conclusion: Non invasive methodologies will be the need in future for accurately predicting how a tumor is going to behave . Whether it’s a grade III or II it can be shown by noninvasive markers ( in our case tumor edema and Hyperintensity in T2WI ) will be boost in managing meningiomas . Hyperitensity of tumour in T2WI was significantly associated with peritumoral brain edema
