Hypertrophic olivary degeneration.
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...

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...

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...

SUMMARY We report DTI and fiber tractography findings in a case of hypertrophic olivary degeneration. A 51-year-old man presented with an abnormal gait and visual difficulties. MR imaging showed enlargement of the right medullary olive and a vascular lesion in the right pontine tegmentum. Fiber tractography showed decreased volume of the right central tegmental tract, supporting a diagnosis of ...
