Compressive optic neuropathy. (A) Coronal T1 post-contrast MRI sequence shows enlargement of the extra-ocular muscles at the orbital apices (arrows). (B) Coronal T1 post-contrast MRI sequence shows the normal appearance of the extra-ocular muscles at the orbital apices. (C) Axial T1 post-contrast MRI sequence shows crowding of enlarged extra-ocular muscles with compression upon the optic nerves (white arrows). Note sparing of the tendinous insertions of the extraocular muscles (black arrow). (D) Axial T1 post-contrast MRI sequence shows a normal appearance of the extra-ocular muscles.
