Vascular Eagle's Syndrome: Two Cases Illustrating Distinct Mechanisms of Cerebral Ischemia.

We report two cases of Vascular Eagle's Syndrome, which demonstrate two distinct mechanisms of cerebral ischemia. In the first case, hemodynamic transient cerebral ischemia arose as a direct result of compression of the internal carotid artery (ICA). In the second, embolic large left middle cerebral artery (MCA) infarction as a result of a thrombus from a pseudoaneurysmal dilatation of the left ICA.
