Well-defined right frontal parafalcine broad-based extra-axial mass abutting the superior sagittal sinus, isointense to the cortical grey matter on T1, T2, high signal FLAIR with areas of low signal on GE (calcifications). The postcontrast sequences show vivid enhancement of the solid component with a central area of cystic changes. A dural tail sign is well-demonstrated on postcontrast sagittal and coronal sequences with reactive hyperostosis of the cranial vault. A rim of CSF signal is noted around the mass on T2 sequences representing the "CSF cleft sign", indicating its extra-axial location. No significant mass effect on the midline structures.
