ABSTRACT
Transsynaptic degeneration in the cerebellum and brainstem may give rise to a rare neurological condition with various clinical manifestations, namely hypertrophic olivary degeneration. The classical manifestations of hypertrophic olivary degeneration comprise myoclonus, palatal tremor, ataxia, and ocular symptoms. Any lesions interrupting the dentate-rubro-olivary pathway, referred to as the anatomic Guillain-Mollaret triangle, contribute to the broad aetiologies of hypertrophic olivary degeneration. The clinical diagnosis depends primarily on the associated symptoms and the characteristic magnetic resonance imaging findings. Concerning treatment and prognosis, there are no widely accepted guidelines. Here, we identified 11 cases of hypertrophic olivary degeneration secondary to brainstem infarction from 1964 to the present. Combined with two of our cases, the clinical and imaging findings of 13 patients with hypertrophic olivary degeneration secondary to brainstem infarction were studied. A meta-analysis of case studies gives the correlation coefficient between infraction location and time to develop hypertrophic olivary degeneration as 0.217 (P = 0.393, P > 0.05). At the significance level of P < 0.05, there was no significant correlation between information location and time to develop hyperophic olivary degeneration. The χ2 between infraction location and magnetic resonance imaging findings of hypertrophic olivary degeneration was 8.750 (P = 0.364, P > 0.05). At the significance level of P < 0.05, there was no significant correlation between infraction location and magnetic resonance imaging findings of hypertrophic olivary degeneration. Conclusion based on the analysis of available data suggests that when newly developed or progressive worsening motor symptoms are presented in patients with previous brainstem infarction, a diagnosis of hypertrophic olivary degeneration should be investigated.
