The azygos anterior cerebral artery (AACA) is a large single anterior cerebral artery that supplies both medial territories of the anterior cerebral hemispheres. Occlusion of the AACA can result, therefore, in bifrontal infarction. We report a patient who suffered from a tetraparesis following a bilateral anterior cerebral artery territory infarction due to an occluded AACA and provide a brief review of the literature.
