Improvement of Lingual Dystonia Following Cerebellar Infarction through Botulinum Toxin Injection: a Case Report

  • 1Department of Physical Medicine and Rehabilitation, National Health Insurance Service Ilsan Hospital, Goyang, Korea.


Lingual dystonia is a rare type of dystonia, the main symptom of which varies from intermittent to sustained tongue fixation. Several studies have suggested that the cerebellum may be implicated in dystonia. There are several treatment options available for dystonia, including medication, botulinum toxin injection, and surgical intervention. We chose to inject botulinum toxin into the styloglossus muscle, and the symptoms of the lingual dystonia were improved. We report a case of lingual dystonia following a bilateral cerebellar stroke that responded to treatment with botulinum toxin.
