• The syndrome of opsoclonus and polymyoclonus developed in an infant who had acute meningoencephalitis with ataxia. A low-density cerebellar lesion was noted by computed tomography, subsequently resolving with residual cerebellar atrophy. The infant recovered completely, except for a mild intention tremor. This was the first documentation, to our knowledge, of an acute cerebellar lesion in this syndrome.
