The dentato-rubro-olivary pathway, also known as the Guillain-Mollaret triangle (GMT) or myoclonic triangle, consists of the dentate nucleus, the red nucleus, and the inferior olivary nucleus (ION). GMT is important for motor coordination and control, and abnormalities in this network can lead to various neurological disorders. The present study followed a systematic approach in conducting a review on GMT studies. The inclusion criteria were limited to human subjects with primary objectives of characterizing and evaluating GMT syndromes, and the methodology used was not a determining factor for eligibility...

Hypertrophic olivary degeneration (HOD) is a rare condition caused by lesions of the dentato-rubro-olivary pathway, usually bilateral. We presented a case of a 64-year old male with HOD caused by a unilateral, posterior pontine cavernoma. The patient has not developed the typical palate myoclonus until recently. Isolated hand myoclonus with coexisting asterixis was present for years. This case shows unique HOD symptomatology and emphasizes the important role of MRI in the differential diagnosis of monomelic myoclonus...

Wernekink commissure syndrome is a rare midbrain syndrome with bilateral cerebellar dysfunction,eye movement disorder,and palatal myoclonus.Few cases of this syndrome have been reported in China,let alone those combined with hallucinations and involuntary groping.This paper reports the diagnosis and treatment of a case of Wernekink commissure syndrome with hallucinations and involuntary groping,aiming to enrich the knowledge about this disease for clinicians.

Objective : Hypertrophic Olivary Degeneration is a rare condition causing transneuronal degeneration of the inferior olivary nucleus. Symptoms manifest as progressively worsening palatal tremor, ataxia, and eye movement disturbances that plateau after several months. Though rarely documented in the literature of this specific condition, disconnection of the inferior olivary nucleus from the cerebellum, and cerebellar atrophy represent a pathway to developing subsequent cerebellar cognitive affective syndrome...

BACKGROUND: Hypertrophic olivary degeneration (HOD), a rare form of transsynaptic degeneration, is secondary to dentato-rubro-olivary pathway injuries in some cases. We describe a unique case of an HOD patient who presented with palatal myoclonus secondary to Wernekinck commissure syndrome caused by a rare bilateral "heart-shaped" infarct lesion in the midbrain.

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare condition caused by lesions within the dentato-rubro-olivary pathway, resulting in ocular nystagmus and palatal myoclonus (oculopalatal tremor) but not usually dystonia. Dystonia is an uncommon association, and we present the first reported association of hypertrophic olivary degeneration with bilateral vocal cord dystonia. CASE PRESENTATION: A 33 year old male presented initially with acute hydrocephalus on the background of previous ventriculoperitoneal (VP) shunting for previously treated medulloblastoma...

OBJECTIVE: Behcet's syndrome (BS) is a chronic, relapsing multisystemic inflammatory perivasculitis and can affect any tissue, including the nervous system. Neuro-Behcet's syndrome (NBS) most commonly affects the CNS parenchyma and presents with a subacute brainstem syndrome that includes cranial neuropathies. Here we describe a rare case of palato-pharyngo-laryngeal myoclonus as a manifestation of NBS and discuss it from a laryngology perspective. METHODS: Case report at tertiary care center...

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare condition that can occur after disruption of the Guillain-Mollaret triangle. Clinically, HOD can present with palatal myoclonus with or without oculopalatal tremor, which sometimes results in symptomatic dysphagia and/or speech abnormalities. This condition is commonly associated with vascular lesions, with only three prior reported cases of HOD resulting from intracranial abscess. OBSERVATIONS: An otherwise healthy patient developed multiple intracranial abscesses...

OBJECTIVE: To present cases of atypical palatal tremor (PT) and showcase the variable phenomenology of this condition. STUDY DESIGN: Retrospective case series. RESULTS: PT, or palatal myoclonus, is a movement disorder characterized by brief, involuntary rhythmic muscular contractions of the soft palate. Variants of PT have been described and include synchronous tremors in other branchial arch derivatives including the larynx, pharynx, neck, face, jaw, ocular and also respiratory and trunk muscles...

BACKGROUND: Hemorrhage lesions may lead to bilateral hypertrophic olivary degeneration (HOD) through interruption of the dentato-rubral-olivary pathway. The pathological features of HOD are unusual neuronal trans-synaptic degenerative changes. CASE SUMMARY: A 56-year-old female was admitted to our hospital because her lower extremities and left upper ones were unable to move for 3 mo, and the swelling of her right lower extremities became worse 3 days ago. She had a hypertension history...

A 69-year-old man with a history of pontine hemorrhage 2 years ago noticed binocular vertical diplopia after the stroke. On examination, there was a small-angle incomitant left hyperdeviation that did not fit the 3-step test for fourth nerve palsy and incyclotorsion of the higher eye. On motility testing, there was an obvious pendular nystagmus. Resting tremor of the right hand was noticed on neurological examination. Examination of the oropharynx revealed rhythmic oscillations of the soft palate synchronous with the eye oscillations and hand tremor...

REVIEW
Fardad Behzadi, Peter J Fiester, Dinesh Rao
Hypertrophic olivary degeneration is a rare condition caused by a lesion in the Guillain-Mollaret triangle which leads to trans-synaptic degeneration resulting in the degenerative hypertrophy of the inferior olivary nucleus. This condition presents clinically with palatal tremor but can also produce ocular myoclonus or cerebellar signs. While any lesion that occurs within the Guillian-Mollaret triangle and results in the deafferentation of the inferior olive can lead to hypertrophic olivary degeneration, the most common etiologies include ischemic and hemorrhagic stroke, vascular malformation, neoplasm, and iatrogenic injury related to surgery...

We report autopsy results of a female patient who was confirmed pathologically as having corticobasal degeneration (CBD). This patient presented with progressive gait disturbance at the age of 66 years, and subsequently showed parkinsonism with a right-sided predominance and dementia. She was clinically diagnosed as having possible corticobasal syndrome without palatal myoclonus throughout the disease course. An autopsy at 72 years of age revealed that neuronal loss with gliosis was severe in the substantia nigra and the portion from hippocampal cornu ammonis (CA1) region to the parahippocampal gyrus, and mild-to-moderate in the basal ganglia, thalamus, red nucleus, dentate nucleus, and cerebral cortices, predominantly in the frontal lobe...

BACKGROUND: Palatal tremor (PT) is an uncommon movement disorder that may be classified into symptomatic (SPT) or essential (EPT). The etiology of SPT is varied, with involvement of the Guillain-Mollaret triangle (GMT) and inferior olivary hypertrophy. EPT is associated with ear clicks and normal imaging and may have a functional basis. OBJECTIVES: This study aims to explore the clinical and radiological features of a large cohort of patients with PT. METHODS: This is a retrospective chart review of patients with PT who were evaluated by the movement disorders subspeciality of the neurology department...

BACKGROUND: Hypertrophic olivary degeneration is a rare condition caused by damage within the triangle of Guillain and Mollaret. We discuss the anatomical, radiological, and clinical history of this rare condition. CASE DESCRIPTION: A 32-year-old lady presented with sub-acute headache, photophobia, and dizziness. She also described facial tingling and itching over her nose, and a thirty-minute episode of slurred speech. Magnetic resonance imaging revealed a 12.1 × 11 × 7...
