摘要
Posterior circulation stroke may rarely be associated with occlusive disease in the anterior circulation, such as in the context of a direct （fetal） origin of the posterior cerebral artery （PCA） from the internal carotid artery （ICA）, or in the presence of a persistent trigeminal artery （PTA） or persistent hypoglossal artery （PHA）. Usually, they happened as infarction involving both ipsilateral carotid and posterior cerebral artery territories with carotid atherosclerosis etiology.3 Here, we reported a rare case with cadioembolic occlusion of the ICA presented with infarction mainly in the PCA territory.
