Anastasi S, Grech R. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220212 Description A 30-year-old man underwent MRI of the internal auditory meatus as a routine follow-up after excision of a large left vestibular schwannoma, 2.5 years previously. MRI images showed an incidental finding of left hypertrophic olivary degeneration (figure 1 and figure 2). This phenomenon occurs as a result of Wallerian degeneration of

Bilateral 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...
متن کاملA case of hypertrophic olivary degeneration after resection of cavernomas of the brain stem and review of the literature
Hypertrophic olivary degeneration is a transsynaptic form of degeneration, which is also a result of primary or secondary lesion and can damage the dento-rubro-olivary pathway. The dento-rubro-olivary pathway was first described by Guillain and Mollaret and is referred to as "the triangle of Guillain and Mollaret". Multiple factors can destroy the dento-rubro-olivary pathway, such as surgical o...
متن کاملHypertrophic olivary degeneration following pontine haemorrhage: hypertensive crisis or cavernous haemangioma bleeding?
The clinical and magnetic resonance (MR) features of hypertrophic olivary degeneration are described, along with a rare but treatable cause of this entity-pontine cavernous haemangioma. Hypertrophic olivary degeneration occurs after focal lesions to the dentato-rubro-olivary pathway, typically following a pontine haemorrhage involving the ipsilateral central tegmental tract, the contralateral s...

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...
متن کاملMR imaging of presumed olivary hypertrophy in palatal myoclonus.
Rhythmic palatal myoclonus is a neurologic sign with one of the most precise pathologic correlations. It almost always is associated with hypertrophic degeneration of the inferior olivary nucleus [1] ; however, such hypertrophic degeneration is not always accompanied by palatal myoclonus. The abnormality of the olivary nucleus is thought to be the result of a transsynaptic degeneration due to a...
متن کاملMR imaging evaluation of inferior olivary nuclei: comparison of postoperative subjects with and without posterior fossa syndrome.
BACKGROUND AND PURPOSE Posterior fossa syndrome is a severe postoperative complication occurring in up to 29% of children undergoing posterior fossa tumor resection; it is most likely caused by bilateral damage to the proximal efferent cerebellar pathways, whose fibers contribute to the Guillain-Mollaret triangle. When the triangle is disrupted, hypertrophic olivary degeneration develops. We hy...
