Well-circumscribed extra-axial mass of the anterior cranial fossa along the right olfactory groove. It elicits an isosignal to the cortical grey matter on T1, iso-to high signal T2 and a high signal on FLAIR fat sat with vivid homogeneous enhancement on postcontrast sequences. No calcification or hemorrhagic component on the GE sequence. No significant surrounding vasogenic edema. A mass effect is noted on the falx cerebri.
