Comparison of preoperative and postoperative MRI. The T1- and T2-weighted images show optic neuropathy before the operation. The T1 image shows isointensity (a), and the T2 and FLAIR images show hyperintensity (b, c). There was a significantly enhanced signal in the tumour after the enhancement scan (d). The FLAIR image shows hyperintensity of the left optic chiasma, visual radiation, and bilateral frontal lobe (e, f, g)
