Pearls & Oy-sters: Oculopalatal tremor with one-and-a-half syndrome after pontine hemorrhage.
Yasser Aladdin, MD James Scozzafava, MD, FRCPC Taim Muayqil, MD Maher Saqqur, MD CLINICAL PEARLS 1. The palatal myoclonus in symptomatic cases is usually silent as the involved muscle is the levator veli palatini. This is in contrast to the audible clicking sound (generated by the synchronous collapse of the eustachian tube) in patients with essential palatal myoclonus in which the involved mus...
متن کاملHypertrophic Olivary Degeneration and Palatal or Oculopalatal Tremor
Hypertrophic degeneration of the inferior olive is mainly observed in patients developing palatal tremor (PT) or oculopalatal tremor (OPT). This syndrome manifests as a synchronous tremor of the palate (PT) and/or eyes (OPT) that may also involve other muscles from the branchial arches. It is associated with hypertrophic inferior olivary degeneration that is characterized by enlarged and vacuol...
متن کاملAcquired pendular nystagmus in multiple sclerosis and oculopalatal tremor.
OBJECTIVE Acquired pendular nystagmus occurs mainly in multiple sclerosis (MS) and focal brainstem lesions. In the later case, it is part of the syndrome of oculopalatal tremor. Even though pathophysiology of acquired pendular nystagmus has been clearly characterized experimentally in both etiologies, there is a persisting ambiguity in clinical literature, which leads one to consider both clini...
متن کاملImpulsive head rotation resets oculopalatal tremor: examination of a model.
We have described a neuromimetic model of the interaction between the inferior olive (IO) and the cerebellum that accounts for symptomatic oculopalatal tremor (OPT), a disorder characterized by oscillations of the eyes (nystagmus), palate and other branchial muscles. OPT develops months after some brainstem strokes, in association with hypertrophic degeneration of the inferior olivary nucleus (...
متن کاملOculopalatal tremor and severe late-onset cerebellar ataxia.
Following four recurrent bleedings of a mesencephalic cavernoma within 10 years (figure 1A), a 62-year-old woman demonstrated left kinetic cerebellar syndrome. She then developed oculopalatal tremor (OPT) associated with bilateral inferior olive hyperintensity (figure 1B). Gamma knife radiation was performed, but she developed severe cerebellar ataxia. OPT secondary to brainstem strokes and ass...
