Figure 2. Right frontal low-grade meningioma on conventional MRI: hyperintense on T2w (A) and FLAIR (B) images, with no peripheral edema and a subtle crescent-shaped CSF cleft between tumor and adjacent brain tissue; no significant DWI restriction with moderate-to-high value on ADC map compared to brain parenchyma (C); and iso-hypointense relative to cerebral grey matter on T1w (D), with homogeneous and intense post-contrast enhancement (E, F). CSF: cerebral-spinal fluid; DWI: diffusion-weighted images; ADC: apparent diffusion coefficient
