Figure 1 Axial T1-weighted (450/12/1 [repetition time/echo time/excitations]) magnetic resonance image shows an abnormal isointense mass at the anterosuperior aspect of the left sphenoid sinus (arrow), immediately medial and adjacent to the left optic nerve (arrowhead).

Figure 2 Axial Tl-weighted contrast-enhanced (621/12/1 [repetition time/echo time/excitations]) magnetic resonance image with fat saturation shows abnormal enhancement within the left sphenoid sinus (arrow) and lateral to the left optic nerve (arrowhead).

Figure 3 Left and Right, Coronal T1-weighted contrast-enhanced (475/12/1 [repetition time/echo time/excitations]) magnetic resonance images with fat saturation show abnormal enhancement within the left sphenoid sinus (arrow) and the overlying dura mater (arrowhead), obscuring the left optic nerve. The right optic nerve is normal (open arrow).
