We described a 41-year-old @entity1 with @entity30154 , who presented severe @entity8684 in all the limbs, neck, face and tongue. Especially, the oral area was affected most strikingly. He had difficulty in eating, because he pushed foods out of the mouth with the tongue. He received left posteroventral pallidotomy ( @entity12468 ). His involuntary movements became much less enough for the @entity1 to eat with a spoon in a sitting position by himself. Six months after the first operation, although @entity2358 on the right hand remained reduced, choreoballistic movement appeared on the left side. He received @entity12468 on the right side. The choreoballistic movement was remarkably improved after the right @entity12468 . No @entity16 has been found for 7 months after the second @entity12468 . Bilateral @entity12468 was fully effective as for the improvement of the activity of daily life. The output from the internal globus pallidus (GPi) is well-known to be inhibitory. Therefore, it is understandable that the coagulation of GPi results in improvement of @entity2845 and @entity2003 in @entity1 with @entity191 . However, some clinical reports, including ours, have described the significant reduction of @entity71 choreoballistic movement after @entity12468 . The exact mechanism of these surgical effects has not been elucidated yet, and further clinical and basic studies are needed to answer this question.

[A case of XXXX successfully treated with posteroventral pallidotomy].
