摘　　要：Hemidystonia is frequently due to an underlying structural lesion in the basa l ganglia and thalamus. It has been suggested that a preserved corticospinal tra ct may be required for hemidystonia to manifest. We provide the first report of a patient who presented with rapid- onset hemidystonia precipitated by an acute pontine infarct demonstrated on diffusion- weighted magnetic resonance imaging . Acute dysregulation of pallidal efferents to the pedunculopontine and/or ponti ne afferents to the thalamus may precipitate hemidystonia.Hemidystonia is frequently due to an underlying structural lesion in the basa l ganglia and thalamus.
