case_images: Color Doppler ultrasound images (a and b) showing the pseudoaneurysm fed by the internal carotid artery (red arrow) and a yin-yang pattern (white arrow).

case_images: Color Doppler US showed a yin-yang pattern within the aneurysm and jet flow from the ICA to the aneurysm sac (a sign of pseudoaneurysm) (Figure 1).
case_images: Sagittal volume-rendered three-dimensional (a) and maximum intensity projection (b) images demonstrating an aneurysm (asterisk) originating from the internal carotid artery (red arrow).

case_images: ICA, displacing the artery posteriorly (Figure 2). In addition, CTA revealed narrowing of the lumen and reduced flow in the ICA, distal to the aneurysm (Figure 3).
case_images: Axial (a) and coronal (b) maximum intensity projection images showing poor contrast material filling of the ipsilateral internal carotid artery (red arrow) relative to the contralateral side (white arrow).

case_images: ICA, displacing the artery posteriorly (Figure 2). In addition, CTA revealed narrowing of the lumen and reduced flow in the ICA, distal to the aneurysm (Figure 3).
case_images: Intraoperative images showing dissection of the anatomical layers (a), freeing of the carotid arteries (b), and opening of the aneurysm sac (c and d).
