Computed tomography (CT) scan of the sinuses showed near-complete opacification of the sphenoid sinus with an air fluid level, small amount of fluid in the posterior nasal cavity, and a small focal bony dehiscence of the optic canal in the superior sphenoid sinus with adjacent pneumocephalus (Figure 1). Coronal T2-weighted magnetic resonance imaging (MRI) also showed the site of leak at the optic canal in the right sphenoid and did not show encephalocele or meningoencephalocele (Figure 2).
Pre-operative coronal T2-weighted MRI showing CSF leak without meningoencephalocele from the right optic nerve canal in the right sphenoid sinus.

Intraoperative endoscopic view of right sphenoid sinus with hydrodissection of sphenoid mucosa off of the bone by the CSF leak. There was no encephalocele.

However, fluorescein was not needed due to endoscopic confirmation of the site of the leak as the optic canal in the sphenoid roof (Figures 3 and 4).
Endoscopic view of defect in optic canal in right sphenoid sinus after removal of mucosa. Small bone defect without encephalocele.
