Computer tomography angiogram of the brain demonstrating the presence of a large arterial out-pouching arising from the cavernous part of the left internal carotid artery protruding through a defect at the left superior-lateral aspect of the sphenoid sinus representing pseudoaneurysm, with its tip projecting well into the right side of sphenoid sinus measuring 16 x 8 mm.

A left internal carotid artery cerebral angiogram was performed using the standard projections, as well as oblique projections, and showed an aneurysm arising from the paraophthalmic segment of the internal carotid artery that projects anteriorly and medially into the sphenoid sinus (Figure 5).
Completion angiogram showing near complete obliteration of the pseudoaneurysm with small residual flow into the neck with preservation of the origin and flow into the ophthalmic artery.
