[Myoclonic cerebellar dyssynergia (Ramsay Hunt). Description of 2 cases].

The authors report two cases of dyssynergia cerebellaris myoclonica in siblings. Apart from typical clinical manifestations attention is called to the results of computerized tomography of the brain which demonstrated cerebellar atrophy. This helped in verification of the diagnosis. Comparing these cases with other ones described earlier in the literature the authors conclude that dyssynergia cerebellaris myoclonica is not a separate nosological entity but a syndrome associated with myoclonia.
