N2 - Correct identification of symptomatic high-grade internal carotid artery stenosis from low-grade or total chronic occlusion is critical for patient selection for urgent carotid endarterectomy. Carotid pseudo-occlusion is a flow-related artifact on noninvasive imaging that can lead to an incorrect diagnosis of total internal carotid artery occlusion, thereby denying an eligible patient for appropriate surgical treatment. We present an 82-year-old man with a symptomatic critical internal carotid artery, which was detected on time-resolved 4-dimensional computed-tomography angiography, whereas single-phase computed-tomography angiography, magnetic resonance angiography, and Doppler ultrasonography suggested apparent occlusion. To our understanding, the use of 4-dimensional computed-tomography angiography to identify carotid pseudo-occlusion has not been previously reported.
