Focal myoclonus-dystonia of the leg secondary to a lesion of the posterolateral putamen: clinical and neurophysiological features.
We report on a patient with spontaneous and stimulus-sensitive myoclonic jerks and dystonia of the right leg that had been present since infancy. Magnetic resonance imaging showed a linear area of gliosis confined to the left posterolateral putamen. This is the first report of focal myoclonus-dystonia of the lower limb secondary to a putaminal lesion.
