Rasmussen syndrome (RS) is a rare disorder usually marked by progressive unihemispheric atrophy, unilateral weakness, cognitive/language decline, and refractory focal epilepsy. [1,2] Although the constellation of symptoms is well-described, the syndrome may be clinically heterogeneous, with onset in childhood or early adulthood, varying tempos of progression, and a spectrum of associated neurologic deficits and outcomes. Additionally, some patients display less typical symptoms, such as a movement disorder or infratentorial involvement.
