"Semantic" conduction aphasia from a posterior insular cortex infarction

J Neuroimaging. 1996 Jul;6(3):189-91. doi: 10.1111/jon199663189.


A unique infarction limited to the posterior insula and intrasylvian parietal opercular cortex produced a subtype of conduction aphasia, characterized by a predominance of semantic paraphasias. Temporal lobe hypoperfusion seen on hexamethylpropyleneamineoxime single-photon emission computed tomography in the absence of any signs of ischemia suggested that cortical diaschisis played a role in the emergence of this syndrome.
