title: [Hereditary neuropathy with liability to pressure palsy presenting with an acute inflammatory demyelinating polyneuropathy].
abstract: BACKGROUND
  Hereditary neuropathy with liability to pressure palsy (HNPP) is an autosomal dominant peripheral neuropathy characterized by compressive focal neuropathies and an underlying sensorimotor demyelinative polyneuropathy. It is usually caused by a 1.5 Mb deletion of the PMP22 gene (17p11.2).
  
  
  METHODS
  We describe the case of a 31 year-old woman who presented with acute demyelinative peripheral polyneuropathy affecting the four limbs and elevated cerebrospinal fluid protein content a few days after a viral illness. Acute inflammatory demyelinating polyneuropathy (AIDP, Guillain-Barré syndrome) was suspected. However, electrophysiologic examination suggested HNPP and subsequent genetic testing was confirmatory.
  
  
  CONCLUSIONS
  This case demonstrates that HNPP can present in an acute manner, mimicking AIDP.
