An 82-year-old female presents with an acute stroke. On examination she has fluent speech with intact comprehension. She can write, but cannot read what she has just written. Naming is impaired. What is the most likely localization for her stroke?

ExplanationD. Pure alexia without agraphia is a syndrome that can occur with lesions to the splenium of the corpus callosum and medial occipital lobe, usually on the left side. In this condition, patients are able to write, but they cannot read even something they have just written. This results from loss of connections from visual input centers and language centers. Conduction aphasia comes from lesions to the superior temporal lobe. Lesions to the angular gyrus result in anomic aphasia. Broca aphasia arises from lesions of the posterior lateral frontal lobe. Wernicke’s aphasia results from lesions to the inferior parietal lobule and posterior superior temporal lobe.
