FIG 10.

Non-contrast CT demonstrates low attenuation suggestive of an acute right MCA territory infarction (A). There is subtle high attenuation (arrow) in the right Sylvian fissure suggesting thrombus (B). Coronal and sagittal CTA views demonstrate long-segment thrombus resulting in occlusion (arrow) of the right internal carotid artery (C). Head view (D) demonstrates occlusion of the right middle cerebral artery. Follow-up head CT obtained on the same day as CTA reveals a right middle cerebral artery territory acute infarction and possible infarctions in the left parietal lobe and left temporal region (E and F). Cerebellar infarctions were also present (G).
