Abstract

Global aphasia without other focal neurologic lateralizing signs (GWLS) is an uncommon stroke syndrome. The pathogenesis of GWLS has been thought as the result of multiple cardioembolism. However, a few cases of GWLS with a single lesion have been reported. We report an unusual case of GWLS with a single left superior temporal infarction. A 73-year-old right handed man was admitted with receptive and expressive language impairment without other focal neurologic lateralizing signs. The patient's global aphasia symptom has being 4 weeks after symptom onset. Brain CT showed only one lesion of left superior temporal lobe. Our case notes that the multiple lesions of the speech area are not only necessary to produce GWLS, and it is not necessarily imply a double lesion or an embolic causes.
