We reported 2 cases of anomia for proper names caused by cerebrovascular disease. Case 1 was a 69-year-old man of left temporo-occipital subcortical hemorrhage and case 2 is a 53-year-old woman of infarction in the territory of the insular branch of the left middle cerebral artery. Both cases were alert and right-handed with normal visual field and acuity. Naming of common names were normal. However naming of proper names were disturbed, especially naming of persons and places. They spoke fluently. Auditory comprehension and repetition were normal. Case 1 presented alexia with agraphia simultaneously. There was no lesion in the classical memorial circuit. There have been few reports of cases presenting anomia for proper names. The opposite phenomenon, a selective sparing of naming of proper names, has also been reported. We concluded that anomia selectively for proper names might appear in the patients with focal cerebral damage of the dominant hemisphere under some special condition. Proper and common names might be separately registered, retained or recalled in the brain.
