Posterior cerebral artery (PCA) infarct

Posterior cerebral artery (PCA) infarcts arise, as the name says, from occlusion of the posterior cerebral artery. It is a type of posterior circulation infarction.

Clinical presentation

Symptoms include contralateral homonymous hemianopia and quadrantic visual field defects. Because the PCA supplies the thalamus, PCA infarction can lead to contralateral thalamic syndrome.
