<unk>  secondary to posterior cerebral artery occlusion – may result in syndromes of memory impairment, opposite visual field loss<unk> , and sometimes hemisensory deficits. The PCA supplies the occipital lobe and the medial portion of the temporal lobe. Infarction of occipital cortex typically causes macular sparing hemianopias due to dual blood supply from both posterior cerebral artery and middle cerebral artery. Occlusion of the calcarine artery that results in infarction of the superior part of the occipital lobe causes a lower peripheral visual field defect. Posterior cerebral artery penetrating branch occlusion may result in infarction of the posterior capsule, causing hemisensory loss, and (if low enough) a transient hemianopia may also occur.
