Effect of Ultrasonography-Guided Botulinum Toxin Type A Injection in Holmes' Tremor Secondary to Pontine Hemorrhage: Case Report
نویسندگان
چکیده
Holmes' tremor is a low-frequency rest and intentional tremor secondary to various insults, including cerebral ischemia, hemorrhage, trauma, or neoplasm. Pharmacologic treatment is usually unsuccessful, and some cases require surgical intervention. We report a rare case of Holmes' tremor secondary to left pontine hemorrhage in a 29-year-old Asian male patient who developed 1.6-Hz postural and rest tremor of the right hand. He responded markedly to ultrasonography-guided botulinum toxin type A injection. To our knowledge, this is the first report of Homes' tremor treated with ultrasonography-guided botulinum toxin type A injection with favorable results.

Hypertrophic olivary degeneration (HOD) is a rare type of neuronal degeneration involving the dento-rubro-olivary pathway and presents clinically as palatal tremor. We present a 48 year old male patient who developed Holmes' tremor and bilateral HOD five months after brainstem hemorrhage. The severe rest tremor was refractory to pharmacotherapy and botulinum toxin injections, but was markedly r...

BACKGROUND We peformed a ventral intermediate nucleus (Vim) thalamotomy in a patient with Holmes' tremor and palatal tremor. The frequencies of these movement disorders were 4 Hz and 3 Hz, respectively. Vim thalamotomy stopped the Holmes' tremor but not the palatal tremor. Our observations suggest different mechanisms for these two involuntary movements. CASE PRESENTATION A 57-arm 11 months a...
