Case study: Supratentorial extra-axial dural based well defined lesion in right frontal convexity measuring 4.2 x 2.6 x 3.5 cm (AP x TR x CC) causing moderate perilesional edema and mild mass effect on adjacent brain parenchyma seen.
Dural tail and homogeneous vivid enhancement seen following contrast. The lesion appears iso intense to grey matter in T1WI and hyperintense in FLAIR/T2.

Conclusion :Extra-axial dural based vividly enhancing lesion in right frontal convexity causing moderate perilesional edema and mild mass effect – Imaging features favor meningioma.Mild diffusion restriction seen (hyperintense in DWI with intermediate signal in ADC). No blooming to suggest hemorrhage or calcification. MRS shows choline peak.
