A gapping bony defect is seen in the posterior aspect of the right orbit giving the "Empty orbit sign"
Absent anatomical landmarks of the optic nerve canal,anterior clinoid, superior and inferior orbital fissures.
Right upper eyelid subcutaneous soft tissue thickening, likely representing plexiform neurofibromatosis.
Diffuse atrophic changes of the right cerebral hemisphere.
