Which of the following sites is not involved in a posterior cerebral aery infarct:
Answer is D (Anterior Coex) : Anterior Coex (Frontal lobe) is not involved in posterior cerebral aery infarct Posterior Cerebral Aery infarcts The posterior Cerebral Aery supplies the midbrain, thalamus, lateral geniculate bodies, posterior poion of choroid plexus, occipital lobes, inferior and medial aspect of the temporal lobe and posterior inferior areas of the parietal lobe. Occlusion of the Posterior Cerebral Aery usually results in two common clinical syndromes depending on the areas involved P1 Syndrome Occlusion of the proximal segment of PCA from its origin to its union with the posterior communicating aery P1 syndrome present primarily with the following signs Midbrain signs Thalamic signs Subthalamic signs P2 Syndrome Occlusion of the distal segment of PCA distal to the junction of PCA with the posterior communicating aery P2 syndrome presents primarily with the following signs Temporal lobe signs Occipital lobe signs
Midbrain
Thalamus
Temporal lobe
Anterior Coex
