Transcortical sensory aphasia following a left frontal lobe infarction probably due to anomalously represented language areas.
A 57-year-old right-handed man presented with speech disturbance 1 day prior to his admission. The standardized aphasia test batteries showed transcortical sensory aphasia. MRI revealed a left frontal and insular infarct. Positron emission tomography scans also revealed a glucose hypometabolism in the same region as the infarcted area on MRI. Repeated aphasia testing showed that his aphasia only partially improved.
