Reversible cerebellar gait ataxia with postural tremor during episodes of high pyrexia

Clin Neurol Neurosurg. 1996 Aug;98(3):227-30. doi: 10.1016/0303-8467(96)00029-7.


We describe five patients presenting with high fever and isolated cerebellar gait ataxia. In all these patients, neurological examination revealed dysmetria, intention tremor and postural tremor during sustained posture, all restricted to the legs. Brain MRI was normal. In four of these patients, the recording of leg tremor during sustained postures showed a 3-Hz frequency. Cerebellar gait ataxia resolved within 3-10 days. We suggest that the ataxic gait was due to a reversible dysfunction of the spinocerebellar part of the anterior lobe.
