In patients with acute ischemic stroke, carotid duplex ultrasonography has been used to assess atherosclerotic lesions at the extracranial carotid artery. We reported a unique sonographic finding of carotid artery thrombus in a patient with acute cardioembolic stroke and atrial fibrillation. An 81-year-old woman with atrial fibrillation was presented with dysarthria and left side hemiparesis. She had undergone surgical thrombectomy and angioplasty for her right brachial artery occlusion four days before the stroke onset. Diffusion-weighted MRI revealed multiple territorial infarctions suggestive of acute cardio-embolic stroke. CT angiography showed an occlusion of the right common carotid artery. On B mode ultrasonography, longitudinal intraluminal tortuous cylinderic oscillating thrombus was observed on the right distal common carotid artery to the proximal internal carotid artery. This case illustrates a unique ultrasonographic finding of acute cardiogenic thrombus in the extracranial carotid artery.
