We report a case of synchronous positive and negative myoclonus following pontine hemorrhage. Constant synchronous jerking of the eyes, tongue, face, mandible, larynx, pharynx, and diaphragms persisted during sleep. Jerking of limb muscles occurred during volitional activities, but not at rest.
BACKGROUND
Palatal myoclonus (PM) is the hallmark of hypertrophic olivary degeneration (HOD); however, little is known regarding the association of thalamic lesions and PM. Case presentation: Here, we report a case of deteriorative PM after an acute small ventrolateral thalamic hemorrhage in a
BACKGROUND
Myoclonus is a clinical sign characterized by sudden, brief jerky, shock-like involuntary movements of a muscle or group of muscles. Dystonia is defined as a syndrome of sustained muscle contractions, frequently causing twisting and repetitive movements or abnormal postures. Cases of
Background: Palato-pharyngo-laryngeal myoclonus, a variant of palatal myoclonus, is characterized by involuntary rhythmic movements of palatal, pharyngeal, and laryngeal muscles. Symptomatic palatal myoclonus is classically associated with hypertrophic olivary
Olivary hypertrophy (OH) is not a primary lesion but, rather, develops as a lesion of the Guillain-Morraret triangle, which is composed of the contralateral dentate nucleus, the ipsilateral red nucleus and the ipsilateral inferior olivary nucleus. OH is usually accompanied by palatal myoclonus or
We treated tongue ulcers in a twenty-two-month-old male child with Gaucher disease and several neuronopathic symptoms, including frequent convulsions. Because the patient was always thrusting his tongue and biting with his upper and lower primary incisors during the myoclonus and convulsions,
BACKGROUND
Inferior olivary hypertrophy (IOH) may develop after pontine hemorrhage and may become a pacemaker for symptomatic palatal tremor (SPT). However, there is no information available that elucidates how IOH may affect the functional outcome. The purpose of this study was to investigate how
We report a case of early-phase sporadic Creutzfeldt-Jakob disease (sCJD) complicated by intracerebral hemorrhage (ICH), classified as MM1 + 2C-type based on autopsy. A 61-year-old Japanese man presented to our hospital with speaking difficulties including repeated usage of the same words. He was
BACKGROUND
Cardiac arrest and aneurysmal subarachnoid hemorrhage both cause sudden, severe cerebral hypoperfusion at ictus. Animal studies indicate that the resultant microvascular dysfunction and cerebral perfusion abnormalities are important determinants of the associated cerebral injury in both
Six patients who manifested acquired pendular oscillation (APO) after brain-stem hemorrhage were examined with electro-oculograph. The characteristics of APO in these 6 cases were compatible with those reported in the literature as the syndrome of so-called 'rhythmic palato-ocular myoclonus'. The
We reported three cases with involuntary movements following pontine hemorrhage. All cases had various symptoms indicating brain-stem lesions, but the consciousness and motor functions were not severely disturbed. CT scans showed a small hematoma localized in unilateral pontine tegmentum in all
A 54-year-old Thai male who has suffered from multiple episodes of ischemic and hemorrhagic strokes developed facio-oculo-palatal myoclonus (FOPM) 1 month after the latest episode of the brainstem stroke.The patient presented with semirhythmic, involuntary, An adult patient with macular cherry-red spots, a gargoyle-like physical appearance, cerebellar ataxia, myoclonus, convulsive seizures, and pyramidal tract signs showed a profound deficiency of beta-galactosidase in liver and brain. Thrombocytopathy of undetermined etiology was evident since
