A routine ultrasound examination showed a slightly hypoechoic plaque at the bifurcation of the right common carotid artery and the beginning of the internal carotid artery, leading to stenosis of the beginning segment of the internal carotid artery. The maximum flow velocity at the stenosis was about 272 cm/s, and the flow velocity near the proximal end of the stenosis was about 81 cm/s. The PSVICA/PSVCCA was 3.36. According to the NASCET standard, the diameter stenosis rate was about 58.4%. A slightly hypoechoic attachment was observed at the distal end of the plaque, which showed slight movement with the pulsation of the carotid artery. The color Doppler also showed a suspicious filling defect
