View larger version (99K): [in this window] [in a new window]   Figure 1. (a) Contrast-enhanced magnetic resonance angiography frontal maximum intensity projection view showing focal dilatations at the common carotid artery bifurcations bilaterally (arrows) suggestive of pseudoaneurysms; (b) coronal and (c) axial magnetic resonance direct thrombus imaging images show eccentric high signal at the site of the suspected pseudoaneurysms representing intraplaque haemorrhage; (d) surgical specimen from the right carotid artery opened to demonstrate intraplaque thrombus. VB, vertebral body.

(a) Contrast-enhanced magnetic resonance angiography lateral maximum intensity projection of the left carotid and vertebral arteries showing "saccular" high-signal structure at the carotid bifurcation and the unopacified left internal carotid artery (ICA). (b) Axial magnetic resonance direct thrombus imaging (MRDTI) image at the bifurcation showing high-signal intraplaque haemorrhage surrounding the ICA origin. (c) MRDTI coronal image demonstrating the intraplaque haemorrhage (large arrow) and a tail of high-signal thrombus extending along the course of the left ICA (small arrows).
