Involuntary movements with cerebellar tumour.
We describe a child with a cerebellar astrocytoma who presented with paroxysmal segmental rhythmic myoclonus. The movement disorder was characterized by focal onset in the left eyelid followed by a sequential march of clinical events. There were no clinical or laboratory findings to suggest brainstem infiltration or cerebral involvement. Marked clinical improvement followed tumour resection. We suggest that the cerebellar lesion was primarily responsible for the movement disorder.
