[Cerebellar vincristine toxicity (author's transl)]

The diagnosis of Wilms tumor stage IV was established in a girl of 5 1/2 years of age in July 1972. Nephrektomy was followed by radiotherapy of the tumorbed and the lung metastasis. Thereafter the child was treated with Vincristine (VCR) and Actinomycine D (AMD) for two years. The child has been off treatment for the last 14 months and is free of disease. An intention tremor of the right hand was noted 4 weeks after the 32nd application of VCR and 2 weeks after a viral infection of unknown etiology. The writing proved to be hypermetric. There was no loss of proprioception and thus the symptoms were localized into the right cerebellum. Having excluded other causes (hemorrhage, metastasis) as far as possible and considering unilateral cerebellar encephalitis as very unlikely the cerebellar symptoms were thought to be VCR toxicity.
