Summary
The present article describes a patient with ischemia in the vascular territory of the posterior inferior cerebellar artery, who developed, in addition to other typical signs of the dorsolateral medulla oblongata, myoclonic movements of the ipsilateral vocal cord.
The essential neuropathological lesion is considered to be an impairment of the dentato-olivary system. In this respect there is a close relationship to other types of rhythmical myoclonus due to lesions of the brain-stem and cerebellum.
Zusammenfassung
Es wird die Krankengeschichte eines Patienten beschrieben, der infolge rezidivierender Infarkte im Strombahngebiet der A. cerebelli inferior posterior neben den typischen Symptomen der dorsolateralen Medulla oblongata ipsilaterale Stimmbandmyoklonien bekam.
Als wesentliches neuropathologisches Korrelat ist eine Läsion des dentato-olivären Systems anzunehmen. Insofern bestehen enge Beziehungen zu anderen rhythmischen Myoklonusformen, die nach Hirnstamm- und Kleinhirnschädigungen auftreten können.
