Case Discussion

Occlusion of the artery of Percheron results in bilateral medial thalamic and rostral mesencephalic infarction with a relatively symmetrical distribution (artery of Percheron infarct). From a practical standpoint, these infarcts should be recognized as due to occlusion of a possible single rare artery that is a normal anatomic variant showing its peculiar supply and not be blamed on occlusion of multiple vascular territories.
