Bálint syndrome (simultagnosia, optic ataxia, and ocular apraxia) is typically caused by pathology affecting the parietal-occipital regions bilaterally. Visual allochiria is an uncommonly reported symptom associated with parietal lobe pathology in which visual stimuli presented to one hemispace are transposed to the opposite side. We describe a patient with Bálint syndrome and visual allochiria whose initial brain MRI demonstrated acute infarction of the right parietal-occipital region. Repeat imaging 9 days later revealed bilateral parietal-occipital infarctions consistent with the observed clinical syndrome. Reversible cerebral vasoconstriction syndrome is introduced as a novel cerebrovascular etiology of Bálint syndrome.
