Meningiomas are the most common non-glial tumours of the central nervous system (CNS), accounting for between 16 and 20% of all intracranial tumours. This study was set up to determine the role of diffusion weighted imaging and determination of apparent diffusion coefficient (ADC) values to differentiate typical meningiomas from atypical/malignant variety.
In this cross-sectional study, 40 patients aged 24–70 years with meningiomas were included. Using routine MRI sequences, the meningiomas were diagnosed and DW images were performed. Apparent diffusion coefficient (ADC) values were measured in the lesion, in the normal area of brain parenchyma analysis. P < 0.05 was considered significant.
27.5% in age group 40–49, 80% typical characteristics meningiomas, cerebral convexity location was found in (30%), the mean ADC of atypical/malignant meningiomas (0.61±0.09) was significantly lower compared with benign meningiomas (1.22 ± 0.1).
Typical meningiomas have higher ADC values than atypical cases. DW MRI may be of help in differentiating typical and atypical meningiomas.
