Carotid pseudo-occlusion

Carotid pseudo-occlusion refers to apparent occlusion of the cervical internal carotid artery on CT angiography or digital subtraction angiography due to a stagnant column of unopacified blood proximal to terminal T-junction occlusion by thromboembolism 1,2

It is important not to mistake this for true occlusion, carotid dissection or a tandem lesion
