A 67-year-old man with an unremarkable personal history presented to the emergency department because of clumsiness accompanied by numbness in his left limbs and an unsteady gait for 6 hours. On neurological examination, he had left hypoesthesia, agraphestesia, and mild ataxia in his left limbs, plus a mild ataxic gait. Other items of the neurological examination had normal results.

All tests for typical and atypical causes of stroke had unremarkable results. A first brain magnetic resonance imaging showed a punctate hyperintensity in left parietal cortex on diffusion-weighted imaging (Figure 1A). Six days later, after an almost complete recovery, he was discharged from the hospital.
