Magnetic resonance imaging on admission and 75 days after admission, single-photon emission computed tomography with I123-N-isopropyl-iodoamphetamine, and electroencephalography on admission. Axial T2-weighted (a) and T2* (b) magnetic resonance imaging on admission, demonstrating left occipital subcortical hypointensity. c Diffusion-weighted imaging on admission demonstrating slight cortical hyperintensity in the surrounding area of subcortical T2 hypointensity. Each lower panel is a higher magnification image of the occipital lobes. f, g, and h are higher magnification images of T2-weighted, T2*, and diffusion-weighted magnetic resonance imaging performed 75 days after admission, respectively, showing recovery. d Single-photon emission computed tomography with I123-N-isopropyl-iodoamphetamine demonstrated increased perfusion in the left dominant occipital lobe. e Electroencephalography demonstrated decreased alpha waves in the left occipital lobe
