a1–e3. Follow-up magnetic resonance imaging obtained 25 days after admission showed symmetrical abnormal signals in the bilateral posterior limb of the internal capsule, putamen, extern al capsule, and insular lobe. The signals were hypointense on T1-weighted imaging sequence (T1WI) (a1, white arrows) and hyperintense on T2-weighted imaging sequence (T2WI) (b1, white arrows), (c) fluid-attenuated inversion recovery, and (d) apparent diffusion coefficient . They were not limited by diffusion on (e1) diffusion-weighted imaging (DWI). Strip and dot-like signals, which were isointense and slightly hypointense on T1WI (a1–2, black arrows) and hypointense on T2WI (b1–2, black arrows), can be observed in the lesions. (e2–3) DWI revealed bilateral hyperintensity in the frontal and occipital lobes
