Recurrent alien hand syndrome in a multiple sclerosis case.

Alien hand syndrome is the strange feeling of one's hand behaving independently. This syndrome has rarely been reported in multiple sclerosis (MS) patients. Herein, we present a 34-year-old female MS patient who had recurrent symptoms of alien hand syndrome that were evaluated as MS attacks based on cranial magnetic resonance imaging that showed demyelinating lesions in the corpus callosum. Alien hand syndrome is classified according to the location of the lesion and the presenting symptoms. As such, our patient can best be classified as a callosal alien hand case.
