MRI Signal Abnormalities of the Inferior Olivary Nuclei in Spinocerebellar Ataxia Type 2
Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant spinocerebellar degeneration, associated with extended repeats of the trinucleotide CAG in the ATXN2 gene on the long arm of chromosome 12. Magnetic resonance imaging (MRI) of SCA2 showed significant atrophies of the brainstem, middle cerebellar peduncles, and cerebellum. We report two genetically proven SCA2 patients who showed hype...

palatal myoclonus, tongue fasciculation and ataxic gait. MRI of the brain showed increased T2 and Fluid Attenuation Inversion recovery (FLAIR) signal intensities in the bilateral inferior olivary complex without diffusion restriction (figure 1). Midbrain, pons, and cerebral and cerebellar parenchyma were normal (figure 2). Imaging features were consistent with bilateral hypertrophic olivary deg...

GALAMBOS, ROBERT,JOHANN SCHWARTZKOPFF AND ALLEN RUPERT. Microelectrode study of superior olivary nuclei. Am. J. Physiol. 1 g7(3) : 527-536. I g5g.--The superior olivary nucleus of barbiturate anesthetized cats was explored with microelectrodes. Both slow wave and single unit activity was recorded to clicks, tones and noise delivered to the two ears. The several segments of the superior olivary ...
متن کاملHypertrophy of the Inferior Olivary Nucleus Impacts Perception of Gravity
Interruption of the dentato-olivary projections, interconnecting the dentate nucleus (DN) and the contralateral inferior olivary nucleus (ION), is predicted to interfere with the DN' role in estimating direction of gravity. In a patient with pendular nystagmus due to hypertrophy of the ION secondary to predominantly right-sided ponto-mesencephalic hemorrhage, perceived vertical shifted from clo...
متن کاملBilateral Hypertrophic Olivary Degeneration in Wilson Disease
Hypertrophic olivary degeneration resulting from lesions of the dento-rubro-olivary pathway, also called Guillain-Mollaret-triangle, has been described previously in a number of cases. Reports about bilateral hypertrophic olivary degeneration of the inferior olivary nuclei are very limited, and the magnetic resonance imaging findings of hypertrophic olivary degeneration in Wilson disease have n...
