Artery of Percheron infarction presented with isolated downgaze paralysis: A case report

Isolated downgaze paralysis is the most infrequent expression of vertical gaze abnormalities. Vertical eye movements are controlled by nuclei and circuits located in the thalamic-mesencephalon region, and more particularly the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF...

description Isolated downgaze paralysis is the most infrequent expression of vertical gaze abnormalities. Vertical eye movements are controlled by nuclei and circuits located in the thalamic-mesencephalon region, and more particularly the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF). The Artery of Percheron (AP) is a rare vascular anatomic variation that supplies the paramedian region of the thalami and the rostral portion of the mesencephalon. We present a unique case of isolated downgaze paralysis caused by AP ischemia.
