Case in brief
This report discusses two patients with Holmes tremor associated with cerebellar lesions. MRI findings in both patients indicated Wallerian degeneration of the dentato-rubro-thalamic pathway (DRTP) and suggested involvement of the dentato-rubro-olivary pathway (DROP). The findings indicate that disruption of these pathways may contribute to the development of tremor in this context.
Diagnostic / clinical pearl
Clinicians should consider the involvement of the dentato-rubro-thalamic and dentato-rubro-olivary pathways when evaluating patients with Holmes tremor linked to cerebellar lesions.
