case_images: CT scan, left imaging is an axial view, without contrast, showing complete opacification of all paranasal sinuses with heterogeneous density inside the sinuses; with erosion in the distal part of the right petrous carotid canal abutting the right sphenoid sinus (arrow); right image is a coronal view, showing extensive polyposis with bony erosion in the bony boundaries of the sphenoid sinuses.

case_images: Computed tomography (CT) scan showed complete bilateral heterogenic opacification of paranasal sinuses, suggestive of chronic AFRS (Fig. 1). More importantly, there was some dehiscence of the lateral wall of the right sphenoid sinus near the petrous segment of the right ICA (Fig. 1).
case_images: CT angiography, showing pseudoaneurysmal dilatation at the petrous segment of the right ICA.
