A 60-year-old man developed an acute right hemiparesis with aphasia. He had hypertension and high cholesterol level. Neck ultrasound and conventional MR angiography showed a moderate left common carotid artery stenosis (figure, A). High-resolution MRI, performed at 1.5 Tesla using a post gadolinium T1-weighted EKG triggered black blood turbo spin echo sequence, revealed a large heterogeneous plaque with a high-intensity intraluminal thrombus (figure, B). Prothrombotic state screening was negative. Clot of common carotid artery is rare. Conventional gadolinium enhanced MR angiography may miss the clot. High-resolution MRI may better identify1 the atheromatous plaque with intraluminal thrombus.
