Orbital MRI shows a perineural mass of the left optic nerve (arrows). a A contrast-enhancing lesion compressing and infiltrating the left optic nerve is seen on the initial MRI scan. b A second fat suppression MRI scan shows a perineural T1 hypo-intense mass reaching from the bulbus oculi up to the optic chiasm, with homogeneous contrast enhancement. c Two months after the start with steroids, a distinctly smaller orbital mass is seen on fat suppression MRI scan with residual perineural thickening of the optic nerve without contrast enhancement
