Figure 1

Magnetic resonance images of the brain and orbits. (a) Axial STIR T2W showed questionable mucocele of the right sphenoid sinus or sphenoidal sinusitis (white arrow) but the architecture of the optic nerve was not well defined. (b) Coronal FLAIR T2W showed right sphenoidal pathology but the right optic nerve was not well delineated.
