In five patients with aphasia occurred after the operation of hematoma or aneurysm of left hemisphere, “nonaphasic” misnaming associated with disorientation, denial of illness and mood changes was observed. Brain CT scan revealed lesions in medial occipital, inferior temporal or anterior frontal lobe, basal ganglia or thlamus of dominant hemisphere.     Based on the analysis of misnaming and the location of lesions, “nonaphasic” misnaming seems to be classified into Group 1., cases with irrelevant paraphasia and irrelevant utterance (case 1,2), Group 2., cases with monemic paraphasia and irrelevant utterance (case 3,4), Group 3., cases with predominantly irrelevant paraphasia (case 5), and Group 4., cases with nonaphasic misnaming caused by the lesion of right hemisphere.
