Noncontrast T1WI and T2WI (with fat suppression) demonstrate thickening
of the intraconal segment of the right optic nerve/sheath. Also noted is abnormal
T2 signal within the marrow of the right posterolateral orbital wall.
On axial and coronal T1W post Gd (fat suppressed) images there is diffuse
enhancement along the right optic nerve sheath and periphery of the optic nerve,
as well as within the marrow of the adjacent lateral orbital wall.
