case_images: (a) Magnetic resonance imaging of the orbits revealing an enhancing, ill-defined lesion centered in the left CS, including involvement of Meckel's cave, superior orbital fissure, orbital apex, foramen rotundum, foramen ovale, and middle cranial fossa. This creates mild narrowing of the patent right cavernous internal carotid artery. (b) Magnetic resonance imaging of the brain revealing enhancing, ill-defined lesion centered in the left cavernous sinus, including involvement of Meckel's cave, superior orbital fissure, and orbital apex. The lesion approaches, but does not primarily or significantly involve the optic nerve.

case_images: Meckel's cave, superior orbital fissure, orbital apex, foramen rotundum, foramen ovale, and middle cranial fossa (Figure 1). Mild narrowing of the patent right cavernous internal carotid artery was also described.
