Axial T2-weighted (A), T1-weighted (B), T1-weighted post-contrast fat saturation (C) MR images show an aneurysm in the left ICA cavernous segment (arrows). Note that the lumen of the aneurysm is hyperintense on T1-weighted images and is filling with contrast on post-contrast images.

On cranial MRI and MR angiography, an aneurysm (15 mm in diameter) of the cavernosal segment of the left ICA was detected (Figures 1, 2).
MR angiography reveals the dissecting aneurysm (arrow). Note that the left ICA shows diffuse luminal narrowing in comparison to the right ICA.

On cranial MRI and MR angiography, an aneurysm (15 mm in diameter) of the cavernosal segment of the left ICA was detected (Figures 1, 2).
Diagnostic DSA of the left ICA shows focal luminal stenosis (arrow) secondary to dissection at the cervical segment (A) and an aneurysm (arrow) in the cavernous segment (B).

A dissecting aneurysm extending into the cavernous sinus was also detected in the cavernosal segment of ICA (Figure 3).
After the second embolization, a near-complete occlusion of the aneurysm with a minimal neck remnant was achieved (arrow).

Follow-up angiograms revealed a near-complete occlusion of the aneurysm and normal distal branches (Figure 4).
