Alexia without agraphia associated with spleniogeniculate infarction. Pure alexia, following an infarction in the distribution of the left posterior cerebral artery, is attributed to damage of the left occipital lobe and the splenium of the corpus callosum. We describe a case of pure alexia in a 57-year-old woman with infarction of the left lateral geniculate body and the splenium of the corpus callosum, a variation on this classic disconnection syndrome.
