Description
Summary:Ischemic stroke in the Posterior Cerebral Artery (PCA) territory is an uncommon entity. Majority present with visual field defects while isolated visual perceptual abnormalities are an exceptional manifestation. About 60 year old hypertensive patient presented with vague symptoms of blurring of vision and palinopsia. Defective color vision was recorded in superior quadrants. Perimetry revealed bilateral congruous left superior quadrantanopia. Magnetic Resonance Imaging (MRI) disclosed right PCA infarct involving occipito-temporal region. This case highlights a rare presentation of PCA stroke with palinopsia and cerebral dyschromatopsia. Perimetric examination coupled with urgent neuroimaging helps the clinician in prompt diagnosis of neurological event causing unexplained visual phenomena.
