There is a broad-base extra-axial mass centered on the right sphenoid wing with a mass effect on the frontal lobe. It elicits an isosignal to the cortical grey matter on T1 and T2, slight high signal on FLAIR with vivid homogeneous enhancement on postcontrast sequences with a "dural tail sign".
Small vessel chronic ischemic changes of the white matter are noted,
MRI features are most consistent with a sphenoid wing meningioma.
