Focal dystonia of acute onset is indicative of a structural lesion in the nervous system. Cerebellar lesions have rarely been associated with dystonia. Case Description: A 42-year-old woman was admitted to the neurology ward because of fever, confusion, and gait unsteadiness. She was diagnosed as having tuberculous meningitis, and, after a few days of antituberculous treatment, she developed prominent dystonia of the left upper limb. Cranial nuclear magnetic resonance imaging showed an isolated

Conclusions: In the patient described, the presence of upper-limb dystonia ipsilateral to a focal cerebellar lesion and the resolution of the dystonia and the mass lesion following treatment suggest that the cerebellum or its connections to the thalamus and/or basal ganglia could be involved in the pathophysiology of the dystonia.
