    A 24-year-old woman diagnosed with Rasmussen encephalitis at age 6 was examined for involuntary movement.


    (Figure: Brain MRI findings at age 24; AB: Axial and coronal FLAIR showing right frontal lobe atrophy, subcortical hyperintensity, caudate head and lentiform atrophy, and compensatory ipsilateral anterior horn [ex vacuo] enlargement [arrow]; no diffusion restriction or gadolinium enhancement observed)

    (Video: Valproic acid-induced reversible hemilateral choreoathetosis; valproic acid-induced left-sided choreoathetosis in a woman with a history of Rasmussen encephalitis; patient lying supine, sitting, and walking can be observed at all times; it is worth noting that even in chorea that persisted for 13 years, after valproic acid withdrawal, the chorea-like movements ceased impressively)
