We report a right-handed 68-year-old man who showed transcortical sensory aphasia. CT and MRI revealed a subcortical infarct circumferenced under the left inferior frontal gyrus. Although this patient had a lesion limited to the subcortical white matter of the so-called "Broca's area", <SUP>123</SUP>I-IMP SPECT and three-dimensional surface display of the brain perfusion revealed a broad cortical hypoperfusion in the inferior frontal gyrus extending to the middle and superior frontal gyrus without involvement of the pre-and post-central gyri. Interruption of the subcortico-cortical neural circuits may lead to cortical hypoperfusion and result in transcortical sensory aphasia. Cases of transcortical sensory aphasia following subcotrical lesions are considered to be relatively rare.
