Central pontine myelinolysis: diagnosis by computed tomography, magnetic resonance and evoked potentials.

The intravital diagnosis of central pontine myelinolysis has become possible with the introduction of computed tomography and magnetic resonance into neurological diagnostics. These tools are of special value when neurological signs of a ventral pontine lesion are lacking, as in the case we describe. Auditory evoked potentials likewise confirm their diagnostic value with regard both to the site of the lesion and to its dorsal extent toward the pontine tegmentum.
