Figure 2: Optic nerve study. (a) Coronal contrast-enhanced T1-weighted magnetic resonance (MR) image shows the expansion of the sphenoid sinus and displacement of intracranial structures. The optic nerves are visible as they are passing through the sphenoid sinus (arrowheads). Polypoidal lesions are visible in both right (white arrow) and left sphenoid sinuses (surrounding the optic nerve). (b) Axial contrast-enhanced T1-weighted MR image demonstrates the fullness of the sphenoid sinus on the left side with direct contact of the optic nerve with mucocele material. Note the expansion of ethmoidal sinuses that are packed with contrast-enhanced lesions that are consistent with the diagnosis of intranasal polyps. (c) An optical coherence tomography scan of the peripapillary nerve fiber layer shows a significant loss of retinal nerve fiber layer in the left eye
