We herein report a patient who developed transient prosopometamorphopsia restricted to the left eye caused by ischemia of the right splenium of the corpus callosum. A 66-year-old right-handed woman suddenly noticed that the left eyes of people she encountered appeared markedly adducted to their noses. On emergent admission, neurological and ophthalmological examinations revealed no abnormalities. Diffusion-weighted magnetic resonance imaging showed a small, hyperintense lesion at the right splenium of the corpus callosum. In this case, information on the right visual field projected to the left occipital lobe might have been obstructed on transmission to the right hemisphere through the splenium of the corpus callosum.
