Computer tomography (CT) scan confirmed the diagnosis with evidence of mucosal thickening occupying the left sphenoid sinus (Figure 1).
(a) Axial slice CT paranasal sinus at the level of sphenoid sinus with white arrow
showing contrast-enhanced lesion within the right sphenoid sinus with involvement of
cavernous sinus. (b) Note the bony dehiscence on coronal slice at the superior sphenoid
wall, pointed out with black arrow.

CT scan showed a contrast-enhancing lesion in the right sphenoid recess involving the right cavernous sinus through a bony dehiscent at the superior sphenoid wall (Figure 2).
(a, b) Axial and coronal slice CT paranasal sinus at the level of sphenoid sinus with
white arrow showing hyperdensities within the mucosal thickening in the left sphenoid
sinus. (c) The axial slice clearly demonstrated the pathological involvement of left
orbital apex (obliterated fat, black arrow) as compared to the normal right side.
