Abstract

A 73-year-old woman developed visual disturbances in the right side of the visual fields along with headache. A neurological examination showed right upper quadrantanopsia and right hemiachromatopsia. She reported that she could only see in shades of gray in the right hemifield. She also had difficulties in recognizing and naming the colors of objects presented in the right hemifield. A color-sorting test revealed generalized impairments involving all color axes. A brain MRI showed acute infarction in the left fusiform and lingual gyri.Key Words: Hemiachromatopsia, Fusiform gyrus, Lingual gyrus
