Axial T1 and T2WIs (left) through the orbits demonstrate enlarged optic
Axial post-contrast images (right) reveal enhancement along both optic
nerve sheaths. On the right side, the enhancement also extends posteriorly
along the lateral wall of the cavernous sinus onto the adjacent tentorium.
Axial and coronal post-contrast T1WIs show additional enhancing lesions
in the anterior falx and over the right orbit. The enhancement of the optic
nerve sheaths extends intracranially and joins over the planum sphenoidale.
