An Unusual Cause of Vertebral Artery Dissection: Esophagogastroduodenoscopy
Figure 1
Brain MRI. (a) T2 sequence; a crescent-shaped filling defect is noted in the distal portion of the right VA (solid arrow). This lesion showed enhancement after intravenous infusion with gadolinium. (b) Fat-saturation sequence; a hyperintense lesion is noted in the third segment of the right VA (solid arrow). These findings are consistent with intramural clot formation and suggest vertebral dissection. For comparison purposes, the normal flow void in the left VA is shown (discontinued arrow). (c) Diffusion weighted image; a hyperintense lesion is noted in the right lateral medulla consistent with ischemic stroke.
