β¦ Synopsis
Three cases are presented with a predominantly axial postural tremor, without visible palatal tremor. Tremor varied in frequency between 3 and 10 Hz, often jumping from one frequency to another in this band. All three patients had evidence of cerebellar pathology. Cases 1 and 2 developed tremor in the setting of a late-onset cerebellar degeneration and after excision of a right cerebellar haemangioblastoma, respectively. Etiology was unclear in Case 3. Nevertheless, this patient had a cerebellar dysarthria. The tremor was similar to that sometimes seen in conjunction with palatal tremor, and EMG studies in Case 3 demonstrated a subclinical modulation of palatal muscle activity simultaneous with the truncal tremor. It is suggested that an axial postural tremor may be due to pathology of the cerebellum and its outflow pathways, despite the absence of clinically apparent palatal tremor.
