PCA Infarction With Its Cognitive Findings: More Than Hemianopia

Abstract

Posterior cerebral artery infarctions constitute 5-10 % of all ischemic strokes.In this case report, a 62 year-old man presenting with right hemiparesia and dysarthria is going to be discussed. The patient had acute onset- demential symptoms and difficulty in reading, and acute infarction in the territory of left posterior cerebral artery was detected in cranial magnetic resonance imaging. The patient who had acute ischemic lesions in left parahippocampus, splenium of corpus callosum, left fusiform gyrus and left thalamus was evaluated with detailed neuropsychological tests. Cognitive deficits severe enough to affect daily living were detected. Pure alexia, anterograde amnesia and anomia, being often neglected manifestations of unilateral posterior cerebral artery infarction, are going to be reviewed with corresponding radiological findings.
