Symptomatic palatal tremor is potentially the result of a lesion in the triangle of Guillain-Mollaret (1931) and is associated with hypertrophic olivary degeneration (HOD) which has characteristic MR findings. The triangle is defined by dentate efferents ascending through the superior cerebellar peduncle and crossing in the decussation of the brachium conjunctivum inferior to the red nucleus, t...

Intracranial calcifications are associated with a variety of disorders, but marked pontine calcification without an underlying structural lesion has rarely been reported. Here we present a unique case with progressive ataxia palatal tremor (PAPT) associated with marked pontine calcification. A previously healthy 53-year old woman first noticed balance problems, slurred speech, and a constant oc...

BACKGROUND The pathophysiology of the movement disorder progressive ataxia with palatal tremor (PAPT) is unclear. CASE REPORT A 77-year-old male presented with dysarthria, ataxia, and 1-2 Hz palatal tremor. A diagnosis of probable sporadic PAPT was established. Brain magnetic resonance imaging was normal at the presymptomatic phase but later showed olivary hypertrophy. Brain [(18)F]-fludeoxyg...

purpose: transcranial magnetic resonance guided focused ultrasound (mrgfus) is a new development in the field of functional neurosurgery. a comprehensive review of the current literature was performed to evaluate of transcranial mrgfus in treatment of essential tremor (et) and parkinson’s disease. methods: articles available in electronic databases of pubmed, and web of science, as of july 2016...

INTRODUCTION Palatal tremor, characterized by rhythmic contractions of the soft palate, can occur secondary to pathology in the dentato-rubro-olivary pathway, or in the absence of such structural lesions. Its pathogenesis is only partially understood. We describe a case of probable drug-induced palatal tremor. CASE PRESENTATION A 27-year-old Indian man had taken carbamazepine and lithium for ...

Palatal tremor is a rare movement disorder characterised by continuous involuntary rhythmic movements of the soft palate, sometimes including other muscles innervated by cranial or spinal nerves. The condition may be essential or symptomatic [1]. We describe a case of symptomatic palatal tremor associated with hypertrophic olivary degeneration (HOD) following multiple brainstem abscesses caused...

Palatal tremor has been subdivided into essential (EPT) and symptomatic palatal tremor (SPT). A subgroup of the SPT form has a syndrome of progressive ataxia and palatal tremor (PAPT). Published details of cases of PAPT are sparse and the disorder appears heterogeneous. We present clinical and MRI features of six patients with sporadic PAPT who attended The University Health Network between 199...
