[Exogenous-toxic bilateral basal ganglia necroses in computer tomography].

By means of cranial computer tomography, it is possible to demonstrate the cerebral consequences of severe intoxications in vivo. A variety of different toxic agents produce similar disease patterns, which are thought to be due to fall in blood pressure caused by the toxin. The lesions are mainly localised in the basal ganglia at the borders of contiguous vascular territories. Six patients observed by the authors are described.
