[Davidenkow syndrome].

A 31-year-old female had since childhood walking difficulties on her right foot. She subsequently developed a right-sided scapuloperoneal amyotrophy with mild distal sensory sings. Nerve conduction velocities and nerve biopsy showed a peripheral neuropathy, and the case was thought to be an example of Davidenkow's syndrome. At the age of 41, the musculature innervated by the right V, VII, XI and XIIth cranial nerves became impaired and this suggested that the lower motor neuron was also involved precluding this picture from inclusion among the Hereditary Motor and Sensory Neuropathies (HMSN) to which Davidenkow's syndrome has been related.
