Oblique, sagittal ultrasound view of a large pseudoaneurysm with patent carotid artery lumen and large amount of intraluminal thrombus, initially reported as "dense scar vs. thrombosed aneurysm".

To evaluate his left carotid bruit, a bilateral carotid artery Doppler study (CADS) showed "a very prominent plaque/scar tissue vs. thrombosed aneurysm at the right carotid artery bulb without significant carotid artery stenosis on both sides" (Figure 1).
Coronal view of head/neck CT depicting a large pseudoaneurysm (black arrow-heads, measured at 55 mm in length and 30 mm in width) at the bifurcation of carotid artery bulb.

Subsequent CTA (Figures 2 - 4) confirmed a giant PA (measured at 55 mm x 30 mm) at distal right common carotid artery (2/3 of it was filled with intraluminal thrombus) without mass effects on native vessels or hemodynamic stenosis of right carotid artery.
Sagittal CT image of pseudoaneurysm (outlined by interrupted, white line), partially filled with thrombus.

Subsequent CTA (Figures 2 - 4) confirmed a giant PA (measured at 55 mm x 30 mm) at distal right common carotid artery (2/3 of it was filled with intraluminal thrombus) without mass effects on native vessels or hemodynamic stenosis of right carotid artery.
Sagittal CT imaging obtained inferior to the level of Figure 3. The pseudoaneurysm is outlined by interrupted, white line, and largely filled with thrombus.

His follow-up CADS showed the stent-graft was widely patent with resolution of his pseudoaneurysm (Figures 5 and 6).
