Imaging from patient 1. (A) Coronal and (B) axial computed tomography
scans demonstrating bony erosion of the right sphenoid sinus (arrow).
(C) Axial T1 postcontrast magnetic resonance imaging demonstrating
classic "onion peel" layering of right internal carotid pseudoaneurysm
(arrow).

Review of computed tomography and magnetic resonance imaging showed that instead of being a true mass within the sphenoid sinus, a suspected pseudoaneurysm of the internal carotid artery was present ( Figure 1 ).
