CT brain was normal and MRI demonstrated no acute infarct; however magnetic resonance angiography (MRA) revealed total occlusion of the left common carotid artery, including the bifurcation and external carotid artery with some reconstitution of the internal carotid at the level of the siphon from collateral blood flow (Figure 1).
